Frequently Asked Questions about International Standards with Answers

This text is a monthly posting to the USENET groups comp.protocols.iso,
comp.std.misc and comp.std.internat. Its purpose is to give answers to
some of the questions appearing most often in these groups and to
collect interesting information about standards that appeared in USENET

If you have a suggestion how this text might be improved or have a text
that you would like to be added, please send it to Markus Kuhn
<>. Contributions, that I can
simply copy into the text are especially welcome. If you can't send
e-mail, you can also send documents or disks/tapes with material relevant
to the FAQ or the ftp archive (
to Markus Kuhn, Schlehenweg 9, D-91080 Uttenreuth, Germany.

This FAQ is crossposted to news.answers and won't expire there on
well-managed news systems until the next version has been posted. As a
consequence of being crossposted to news.answers, this text will also
be automatically archived on many FAQ servers all over the world
(e.g., look with anonymous ftp at in directory
/pub/usenet/news.answers). You'll also find there many other answers
to frequently asked questions.

This FAQ is perhaps one of the first that uses an 8-bit character set
on USENET, because there are many non-ASCII characters necessary for a
correct ISO member address list. Nearly the full USENET is 8-bit
transparent, and the character set is announced in the message header
as defined in RFC 1341. If you can't see the right characters then
check your environment (fonts, stty settings, newsreader options,
code pages, ...), because the character set ISO 8859-1 is available on
many computers, but often simply not activated. A few test characters are
j=e+^, 5=greek mu, )=copyright sign and ==fraction 1/2. If you see
j, 5, ) and = instead, then the highest bit has been stripped off.
The portable program iso2asc.c that you'll find with anonymous ftp on in pub/doc/ISO/english/ converts ISO 8859-1
text files to 7-bit US-ASCII and to IBM PC character set if you
can't display these characters directly.

Don't be angry if anything in this text is incorrect. As with all
information exchanged on USENET, you only get what you pay for and the
current author isn't paid a single pfennig for this FAQ. Better mail
me the correction!

I hope you enjoy it ...

What are ISO, ITU, CCITT, ANSI, ...?

Many countries have national standards bodies where experts from
industry and universities develop standards for all kinds of
engineering problems. Among them are, for instance,

     ANSI     American National Standards Institute       USA
     DIN      Deutsches Institut fuer Normung             Germany
     BSI      British Standards Institution               United Kingdom
     AFNOR    Association francaise de normalisation      France
     UNI      Ente Nazionale Italiano di Unificazione     Italy
     NNI      Nederlands Normalisatie-instituut           Netherlands
     SAA      Standards Australia                         Australia
     SANZ     Standards Association of New Zealand        New Zealand
     NSF      Norges Standardiseringsforbund              Norway
     DS       Dansk Standard                              Denmark

and about 80 others.

The International Organization for Standardization, ISO, in Geneva is
the head organization of all these national standardization bodies.
Together with the International Electrotechnical Commission, IEC, ISO
concentrates its efforts on harmonizing national standards all over the
world. The results of these activities are published as ISO standards.
Among them are, for instance, the metric system of units, international
stationery sizes, all kinds of bolt nuts, rules for technical drawings,
electrical connectors, security regulations, computer protocols, file
formats, bicycle components, ID cards, programming languages,
International Standard Book Numbers (ISBN), ... Over 10,000 ISO
standards have been published so far and you surely get in contact with
a lot of things each day that conform to ISO standards you never heard
of. By the way, "ISO" is not an acronym for the organization in any
language. It's a wordplay based on the English initials and the
Greek-derived prefix "iso-" meaning "same".

Within ISO, ISO/IEC Joint Technical Committee 1 (JTC1) deals with
information technology.

The International Telecommunication Union, ITU, is the United Nations
specialized agency dealing with telecommunications. At present there
are 164 member countries. One of its previous bodies was the
International Telegraph and Telephone Consultative Committee, CCITT,
which is now after an organizational reorganization of ITU called
ITU-T (Telecommunication Standardization Sector). A Plenary Assembly
of the CCITT/ITU-T, which takes place every few years, draws up a list
of 'Questions' about possible improvements in international electronic
communication. In Study Groups, experts from different countries
develop 'Recommendations' which are published after they have been
adopted. Especially relevant to computing are the ITU-T V series of
recommendations on modems (e.g. V.32, V.42), the X series on data
networks and OSI (e.g. X.25, X.400), the I and Q series that define
ISDN, the Z series that defines specification and programming
languages (SDL, CHILL), the T series on text communication (teletex,
fax, videotext, ODA) and the H series on digital sound and video
encoding. The previous CCIR (International Radio Consultative
Committee and the IFBR (International Frequency Registration Board)
are now called ITU-R (Radiocommunication Sector). The previous BDT
(Telecommunications Development Buereau) is know called ITU-D.

Since 1961, the European Computer Manufacturers Association, ECMA, has
been a forum for data processing experts where agreements have been
prepared and submitted for standardization to ISO, ITU and other
standards organizations.

Why can't I ftp ISO standards?

ISO standard documents are copyrighted by ISO, and their price is much
higher than the costs for printing and shipping the papers. This is
because the expenses of running ISO are covered completely by selling
the standards. ISO has no other source of money for its operation.
Consequently, ISO standards are NOT available as public domain
documents to Internet users.

Many people feel that this is a great disadvantage and ISO is at the
moment examining other methods of distributing the documents (e.g.
CD-ROM, magnetic tapes and online access) but the odds are very low
that ISO standards will become freely redistributable files like
Internet RFCs in the near future (i.e. this decade).

BTW: The costs of actually developing standards is borne by the
thousands of organizations which pay for the time and travel expenses
of the delegates to national and international level meetings.

By a liaison contribution from ISO/IEC JTC1/SC6 to the Internet
Architecture Board (IAB), a very few OSI standards (e.g. ISO 8073, ISO
8473, ISO 9542, ISO 10589) ARE available as PostScript files with ftp
from in directory pub/iso as files,,

Where can I get standard documents?

ISO standards are sold by the national standards body members (e.g.
ANSI, DIN, ...), by special companies, and by the ISO General
Secretary in Geneva. The standard way to order standards is to contact
your national standards body (check the list in the chapter 'What's
the address of my national standards body?'). If you want to get the
standards directly from ISO, you may order them from

     ISO Sales
     Case Postale 56
     CH-1211 Geneve 20


ISO accepts VISA and American Express. They require the card number,
its expiry date, and an authorizing signature. Some people prefer to
order their standards directly from ISO in Geneva, because some
national member bodies (e.g. ANSI) reprint ISO standards locally, use
cheaper paper and charge more for ISO standards then the headquarters.

ISO publishes an 'ISO Bulletin' with information about current
standardization activities and articles about various standards. It
lists all the ISO standards published or withdrawn, the DISs
circulated, the CDs registered, etc. It also has a calendar of all
upcoming ISO meetings. You can get it from your national standards body
or from the General Secretary in Geneva. You may get more information
on this from

     International Organization 
     for Standardization
     Promotion and Press Department
     Case Postale 56
     CH-1211 Geneve 20

ISO publishes an annual 'ISO Catalogue' which lists all ISO standards
currently in force and other ISO publications (e.g. guides and
standards handbooks) with a price code. It contains an entry like

     ISO 4074-2:1980   Rubber condoms--
                       Part 2: Determination of length
                       Ed. 1   2 p.   Code A   TC 157

                       Preservatifs masculins en caoutchouc--
                       Partie 2: Determination de la longueur

for each ISO standard in both English and French and a few other lists.
You have to ask your national standards body how much you have to pay
them for a standard with price code A (e.g. 20 Swiss francs in
Switzerland and 27.10 DM in Germany). The price depends on the number
of pages of the document. Code A means 1 or 2 pages. :-(

You can order all CCITT recommendations from

     International Telecommunication Union
     General Secretariat - Sales Section
     Place des Nations
     CH-1211 Geneve 20

There you can also get a free ITU List of Publications. The 1988 series
of recommendations has been published as the 'Blue Book' (consisting of
Volumes each dealing with a specific topic and bound as "Fascicles" of
a few hundred pages each) which fills about 16,000 pages or a whole
shelf. Not all of the Blue Book volumes are about OSI, the rest deals
with the phone, ISDN, telex and teletex nets, fax protocols,
international tariffs, etc. In the past, CCITT recommendations have
been published in a four year cycle. These publications are identified
by the color of their binding: 1960 red, 1964 blue, 1968 white, 1972
green, 1976 orange, 1980 yellow, 1984 red and 1988 blue. The 1992 White
Book will be the last four year collection of all recommendations.
After this, recommendations will be published separately.

An ITU document ordering form may be retrieved from the ITUDOC server
(see below).

The CCITT 1988 Blue Books are also available from:

     order number, name of purchasing organization, your name, phone
     number and shipping address.

For several years the US company OMNICOM published a newsletter about
OSI development and distributed copies of ISO standards. Document
distribution for OMNICOM (which is out of business) has been taken over
by Phillips Business Information.  The phone number (800) OMNICOM still
works, but is answered by Phillips.

It is highly recommended to compare prices before ordering standards!

How can I get in contact with the committees?

The standard way is to contact the members of your national standards
body. Some of these people will also serve as your country's
representatives to the international organizations.

Only a very few experts active within ISO and CCITT are regularly reading
USENET but most are reachable with Internet mail.

The editor of the new ASN.1 encoding rules standard (ISO 8825) is

     Bancroft Scott <>

The most active participants in the X.gc group working on a news
extension for the X.400 electronic mail protocols similar to USENET are

     Jacob Palme, Stockholm University <>
     Hiromiki Moriyama <>
     Murray Turoff, New Jersey Inst. of Technology <>
     Steve Benford, Nottingham University <sdb@Cs.Nott.AC.UK>

ECMA has email access and the secretary-general can be reached with

ISO also has email access. Two known addresses are

     Michael Smith <>
     Jacques Chabot <>

IEC also is up on Email and is accessable from Internet through
a bridge (that's sometimes down). One address is e.g.:

     Jack Sheldon <>

Where can I ftp CCITT recommendations?

ITU now operates a public document store (ITUDOC). It can be reached
as a mail server and with an interactive telnet/X.29/modem interface
(TIES). Ftp and gopher access are planned.

The mail server is an X.400 "robot" mailbox at ITU headquarters in
Geneva. Its address is:

     X.400: S=itudoc; P=itu; A=archom; C=ch

You can send it messages like

     GET 1449

At the moment, ITUDOC offers short summaries of ITU recommendations
and full text versions of a growing number of documents in various
formats (Word for Windows, Postscript, ASCII).  The project
coordinator for Teledoc is Robert Shaw <>.


     GET 2798

you'll receive a "List of CCITT Recommendations currently in force"
(about 80 pages).

There is also interactive access to ITUDOC and other ITU information
services possible (TIES). The telnet addresses are ( (

Login as GUEST or ANONYMOUS. The X.25 address is #2284681 11112 and
Modem dial-up access is possible with the phone number +41 22 733 7575
(300 to 9600 bps, 8 data bits, no parity, V.42, V.42bis, MNP support).

The Internet address of the ITU gopher server is

There was an experimental ftp server for CCITT recommendations a few
years ago but this service was shut down in the end of 1991 and the
files it provided weren't very high quality (incomplete, missing
graphics and tables). Better use the new official documents from ITUDOC.

Which Internet resources provide information about standards?

The author of this FAQ maintains an archive where information about
ISO standards is collected at anonymous ftp server
in pub/doc/ISO/english. Contact <>

What's the meaning of CD, DIS, IS?

[Posted by Brad Smith <>:]

Replies to an earlier posting of mine indicated a lack of familiarity
with current ISO procedures for developing and gaining consensus on
international standards.  Here are some notes to update you.

The 1989 revision of the ISO/IEC Directives specify the accepted
procedure for developing and approving International Standards.  This
is a complicated process with many activities and critical milestones
so if you do any standards work, you will probably want to get a copy
of the document for reference.


The Directives give a set of procedures for managing the work of a
committee which define five stages of document approval:

       The Proposal Stage
            Voting members ballot on the creation of a new
            standards project.

       The Preparatory Stage
            Project Leader manages the development of a Working

       The Committee Stage
            Consensus is achieved on a Committee Draft.

       The Approval Stage
            National bodies vote on a Draft International

       The Publication Stage
            ISO publishes the International Standard.


The Proposal stage begins with a suggestion for a new area of
standardization activity (see [ISO1] - clause 2.2, page 17).  The
suggestion is documented on an ISO New Work Item Proposal form and is
sent out by the committee's Secretariat to all participating and
observing members of the committee, to all liaison organizations, and
to other national bodies of ISO.  A three-month voting period is
prescribed.  All voting members have an obligation to reply.  

Approval requires a simple majority vote and a commitment by at least
five national bodies to actively participate.  Projects can be placed
within an existing Working Group (WG), or a new WG can be created to
act as a focus for technical development work.  

The Proposal stage ends when a New Work Item is approved, is registered
with the ISO, and is included in the list of projects within the
program of work of the SC-4 Committee.


The Preparatory stage of ISO standards development covers the creation
of a working draft of the ultimate standard (see [ISO1] - clause 2.3,
page 17).  The work is performed by experts from participating
countries organized into working groups and advisory groups under the
guidance of a convener, and further subdivided into project areas each
under the direction of a Project Leader (see [ISO1] - clause 2.1.6,
page 16).  

Different committees may decide on different procedures to govern the
development of working drafts of their standards.  In our committee,
Working Group conveners have been encouraged to subdivide the technical
work into logical tasks each under the direction of a Project Leader. 
Project Leaders report to the Convener of their parent Working Group. 
The Working Group convener usually serves as a Project Leader (see
[ISO1] - clause 2.3.3, page 17) but is additionally responsible for
coordinating any other Project Leaders in the WG as well. 

As technical work is completed by a WG, it is documented in a working
draft of an ISO standard and begins the process of consensus-building
and approval.  Generally, each document has an editor who has custody
of the electronic form of the document, but the project leader has the
overall responsibility for coordinating the efforts necessary to gain
approval of the draft as an international standard.

The ISO Directives do not give details of the process for developing a
working draft within the hierarchy of projects, WGs, and advisory
groups.  That is left for each SC to establish for itself.  Our
committee has a detailed set of procedures which are available if
anyone wants to see them.

The Preparatory stage for any one Part ends when a working draft of
that Part has been approved by the Project Management Advisory Group. 
It is at that time given to the Secretariat of SC-4 who formally
registers the Part as a Committee Draft with ISO (see [ISO1] - clause
2.3.8, page 18).


The Committee stage begins with the circulation of the document in the
form of a Committee Draft (CD) for formal balloting (see [ISO1], clause
2.4.1, page 18 and SC4 Res# 73).  The ballot is sent out by the
committee Secretariat to all participating and observing countries of
SC-4 and also to Class A Liaison organizations.  All recipients are
asked for comments on the CD.  Voting members are asked to vote on the
acceptance of the CD for registration as a Draft International
Standard.  All voting members have an obligation to reply.  A three
month voting period is prescribed.  Ballot comments are collected and
summarized by the Secretariat.  

A team consisting of the Secretariat, the committee Chairman, the
affected Conveners, and the affected Project Leaders review the ballot
comments to determine the degree of consensus obtained.  Based on the
evaluation, a decision is made whether to

       a)  discuss the CD and comments at the next meeting,
       b)  register the CD as a Draft International Standard, or
       c)  ask that a revised CD be prepared for circulation

If at least three voting members of SC-4 disagree with proposal b) or
c) of the Secretariat, the CD will be put on the agenda for discussion
at the next committee meeting.

Failure to attain consensus approval of a Part will trigger
determination c) above and thus cause the document to be returned to
the Working Group level for the preparation of a revised Committee

It should be noted that both an English and a French text must be
available for each Part during the Approval stage which comes next. 
This translation should be instigated at an early date to allow time
for a quality effort.

The Committee stage ends for a CD when the Part is accepted by
committee ballot.  The document is then given to the Secretariat who
formally submits the English and French versions to ISO for
registration of the Part as a Draft International Standard (see [ISO1]
- clause 2.4.7, page 19).


The Approval Stage begins with circulation of the English and French
versions of the Part in the form of a Draft International Standard
(DIS) for formal balloting (see [ISO1] - clause 2.5.1, page 19).  The
ballot is sent out by ISO Central Secretariat to all national bodies of
ISO (our committee members plus others).  Recipients are asked to vote
on the approval of the DIS as an International Standard.  All national
bodies have an obligation to reply.  A six-month voting period is
prescribed.  Ballot comments are collected by ISO and are returned to
our committee.

The DIS is approved if a two-thirds majority of votes cast by voting
members of our committee are in favor and if not more than 25% of the
total number of votes cast are negative.  Abstentions are excluded when
counting votes (see [ISO1] - clause 2.5.3, page 20).  If so approved,
the committee Chairman, in cooperation with the Secretariat, and in
consultation with the ISO Chief Executive Officer makes a decision
whether the document should be published without change or whether an
amendment should be drafted to reflect persuasive technical comments
received (see [ISO1] - clause 2.5.4, page 20).  If an amendment is
drafted, it requires a two-month vote as above.

If the DIS is not approved, the Committee Chairman, in cooperation with
the Secretariat (and, if necessary the Project Leader and the affected
WG Conveners), and in consultation with the ISO Chief Executive
Officer, makes a decision whether to prepare a new DIS for a two-month
vote or to refer the document back to committee for further work (see
[ISO1] - clause 2.5.6, page 20).

The Approval stage ends with the decision of the committee Chairman to
publish.  The Secretariat then prepares the final manuscript and sends
it to ISO.


The ISO Chief Executive Officer does final preparation of the Foreword
and sends the proof back to the SC-4 Secretariat for review.  Further
editorial or technical amendments are unacceptable at this stage.

The Publication stage ends with the release of the document as an
International Standard.

[FAQ author's note: The reference [ISO1] hasn't been resolved in Brad
Smith's original posting, but, according to the ISO Catalogue, the
complete ISO ceremony of creating a standard is defined in:

Harald Alvestrand wrote me, that there is also something called a "CD
ballot" that is needed to get a document from "expert contribution"
status to "CD" status, and that there are exceptions to the "French
required" rules. He has one DIS that says on the cover: "In accordance
with the provisions of Council Resolution 21/1986 this DIS is submitted
in the English language only"]

Another nice explanation :-) has been posted by Chad Fogg <>:

  Here is the evolutionary chart of ISO standards:

  1. Barroom witticism ("NI" or "Napkin Item")
  2. New proposal ("NP" or "Need Permission")
  3. Working Draft ("WD" or "We were Drunk")
  4. Committee Draft ("CD" or "Calendar Deadlock")
  5. Draft International Standard ("DIS" or "Doesn't Include Substance")

Interconnection) protocols is part of the osi-protocols FAQ which is
posted to comp.protocols.iso.

ISO 646    Good ol' 7-bit ASCII with national variants

IEC 824    Terminology related to microprocessors

ISO 2022   ESC sequences for switching between various character sets

ISO 2382   Information technology -- Vocabulary

ISO 3166   Codes for the representation of names of countries.
           This standard defines a 2-letter, a 3-letter and a numeric
           code for each country on this planet. E.g. US/USA/840=
           United States, DE/DEU/276=Germany, GB/GBR/826=United
           Kingdom, FR/FRA/250=France, ...)
           The 2-letter codes are well known in the Internet as top-level
           domain names. The 3-letter versions are often used at
           international sports events.

ISO 4217   Codes for the representation of currencies and funds

ISO 5218   Representation of human sexes
           Sex is represented by a one-character language independent
           numerical code: 0=not known, 1=male, 2=female, 9=not 
           specified. The standard also specifies, that "no significance
           is to be placed on the fact that 'Male' is coded '1' and 
           'Female' is coded '2'.  This standard was developed based 
           upon predominant practice of the countries involved and does 
           not convey any meaning of importance, ranking or any other 
           basis that could imply discrimination." :-)

ISO 6429   ASCII Control Codes, also known as VT100/VT320/ANSI escape 

ISO 6709   Representation of latitude, longitude and altitude of
           geographic positions

ISO 8601   Representation of dates and times.
           This standard defines a lot of details of the calendar.
           E.g. the ISO definition of the week numbers is that the 
           first day (day number 1) of a week is Monday and that the 
           first week in a year (week number 1) is the week that includes
           the first Thursday in January, i.e. the first week that has at
           least four days in January. Other definitions are, e.g., that 
           hours of a day are counted from 0 to 24 and that the
           international notation of dates is the Bigendian format 
           year-month-day, e.g. 1993-04-17 and that for time is 20:36:04.
           There are also string formats for computer applications
           specified that have to represent date and time in files 
           and protocol packets. (See
           english/ for a very detailed summary.)

ISO 8632   Computer Graphics Metafile (CGM). This standard defines
           a file format for 2D vector graphics. Part 1 defines the
           graphic elements (lines, filled polygons, text, colors, ...)
           that may appear in a CGM and the other parts define 3 different
           encodings for these graphic elements:

              Character encoding:  compact ASCII encoding, useful if
                                   CGM files have to be transported
                                   over not binary-transparent channels
                                   (e.g. e-mail, character set converter)
              Binary encoding:     this is the most often implemented
                                   CGM encoding, because it is both
                                   efficient and easy to implement.
              Clear text encoding: a human readable textual encoding.

           This standard format might be exactly what you need if you
           want to store pictures that can be drawn by the usual graphic
           library functions (move, line, set_color, set_linestyle, ...)
           in an resolution-independend way. The format is simple and
           easy to understand. The new 1992 revision of the CGM standard
           contains many additional graphic elements (splines, rendering
           options for ends and joins of thick lines, several color
           models, high quality fonts, grouping of graphical elements, ...)
           that make this format capable of storing images with the quality
           you are used to get from Postscript, Corel Draw, Framemaker,
           etc. The main difference between CGM and Postscript is that
           Postscript is a full programming language while CGM is just
           a simple list of graphical elements which makes CGM suitable
           for reediting.

           known as 'Unicode' that is expected to become pretty
           popular soon and will be supported by Windows NT, Plan 9
           and other new operating systems.

ISO 3      Preferred numbers
           Especially in engineering applications, where a designer often
           has to choose an arbitrary dimension (e.g. the length of a
           part) within a range, it might be useful to have some
           'preferred numbers' defined that should be preferred in these
           situations. These are 1, 1.6, 2.5, 4, 6.3 which might be 
           multiplied or divided by 10 as often as necessary and should be
           used together with SI (metric) units. The above simplest
           set of preferred numbers devides the range from 1 to 10 with 5
           numbers. There are also supersets with more numbers defined, e.g.
           1, 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8. This standard is perhaps
           less relevant in computer science, where programmers traditionally
           use the powers of two (1, 2, 4, 8, 16, ...) multiplied by 1, 3 or
           5 as 'preferred numbers'.

ISO paper sizes

The paper formats defined by ISO in the A, B and C series are used
today in nearly all countries apart from North America.

The formats have been determined according to the following rules:

  - A0 has an area of one square meter.
  - The aspect ratio of all members of the A, B and C-series is
    sqrt(2) = 1.41421...
  - You get the next higher format by cutting the paper in two
    equal pieces parallel to the shorter side. This results again in
    a 1 : sqrt(2) format (that's the big advantage of this format).
  - The size of a B-series paper is the geometric mean between the size of
    the corresponding A-series paper and the next bigger A-series paper.
    E.g. B1 is between A1 and A0.
  - The size of a C-series paper is the geometric mean between the size of
    the A-series and B-series paper with the same number.

This means that the following formulas give the dimensions in meters:

                      Width                   Height
      A-series        2 ^ (- 1/4 - n/2)       2 ^ (1/4 - n/2)
      B-series        2 ^ (      - n/2)       2 ^ (1/2 - n/2)
      C-series        2 ^ (- 1/8 - n/2)       2 ^ (3/8 - n/2)

Larger sizes have smaller numbers.  Sizes larger than those with n = 0
are written as 2 A0 and 4 A0 rather than A(-1) and A(-2).

The following table lists the official definitions of the paper sizes
which are the values from the above formulas rounded more-or-less to
an integral number of millimeters:

      4 A0 1682 x 2378
      2 A0 1189 x 1682
        A0  841 x 1189       B0 1000 x 1414       C0  917 x 1297
        A1  594 x 841        B1  707 x 1000       C1  648 x 917
        A2  420 x 594        B2  500 x 707        C2  458 x 648
        A3  297 x 420        B3  353 x 500        C3  324 x 458
        A4  210 x 297        B4  250 x 353        C4  229 x 324
        A5  148 x 210        B5  176 x 250        C5  162 x 229
        A6  105 x 148        B6  125 x 176        C6  114 x 162
        A7   74 x 105        B7   88 x 125        C7   81 x 114
        A8   52 x 74         B8   62 x 88         C8   57 x 81
        A9   37 x 52         B9   44 x 62         C9   40 x 57
        A10  26 x 37         B10  31 x 44         C10  28 x 40

The most popular sizes are perhaps:

        A0        technical drawings
        A4        letters, magazines, documents
        A5        books
        C4,C5,C6  envelopes
        B4,A3     supported by many copy machines, newspapers

There are also strip formats possible, e.g.

    1/3 A4   99 x 210
    2/3 A4  198 x 210
    1/4 A4   74 x 210
    1/8 A4   37 x 210
    1/4 A3  105 x 297
    1/3 A5   70 x 148

All these formats are paper end formats, i.e. these are the dimensions
of the paper delivered to the user/reader. Other standards define slightly
bigger paper sizes for applications where the paper will be cut to the
end format later (e.g. after binding).

The ISO DL envelope format has the dimensions 220 x 110 millimeters.

(The values have been copied from DIN 476 (Dec 1976) which is the 
German version of the ISO 216 standard).

What is ISO 9000?

Q. I've seen recently announcements of several big companies in
newspapers, where they tell their customers that they now conform to
ISO 9000. What is ISO 9000? 

A. A standard for the development process of a product.

Q. Why has ISO 9000 been written and what does it mean if a company
claims to conform to ISO 9000 ?

A. I think, it means that the product which carries the ISO 9000
certified mark has undergone a well-defined, well-engineered,
well-monitored design/development/testing/production process. (This in
turn is expected to imply that the product is not a result of some
hap-hazard development and thus is of a superior quality.)

The agency which registers a product as ISO registered expects that the
business produce a "Quality Manual". They verify the manual against the
ISO 9000 standards. Then they verify that the design/development/test
etc. processes closely agree with what is mentioned in the Quality
Manual, recommend corrective actions, if any, and after a few periodic
(at least 6 monthly) assesments certify the product as an ISO 9000
registered product.

Q. A few practical examples? 

Basically, it results in "Document everything you do" and "Do what you
have documented". It is expected that there will be a documented
procedure for everything that is done in the design/development/testing
of a product. The ISO inspectors are quite meticulous about these
things. (I heard some of the ISO coordinators relating there

Key changes needed:

   o Training of the full time personnel to understand ISO 9000
     standards, ISO Audit, etc.
   o Alerting all the employees of upcoming ISO audits and having
     periodic educational talks on how to work in a ISO framework.
   o Slowly changing the work habits of the employees so that: They 
     do what is documented and the document says exactly what they 
     are doing.

Key considerations:

   o Financial commitment involved in getting ISO registed. (Close to
     $20k per product over a 2 year period in external costs + internal
     costs in training people work hours lost during the audits (3-5 days 
     a years) + cost of the QC department). [Figures based on UL's 
     ISO 9000 registration figures.]

   o Will the employees be happily willing to work in this tight
     "document everything you do" framework?


   o "ISO approved" seems to be a green signal for the European
     customers to buy a product.

If ISO 9000 is forseen as a "way to go" for the future in US/World then
it would be a good idea to start early.

[I wish to thank Sandeep Phadke <>, who attended a
seminar on ISO 9000 recently, for this USENET interview.]

And here comes a list of the current 91 member bodies of ISO. According
to ISO regulations, only one organization "most representative of
standardization in its country" is allowed to be ISO member body in
each country. Revisions to the following addresses are announced in the
monthly ISO Bulletin. The author of this FAQ has currently no access to
the ISO Bulletin, so it is up to the better informed reader whether this
list will stay up to date. The addresses in this list are from the
official ISO member list from september 1992 and have been typed in as
an 8-bit ISO 8859-1 Latin 1 file by Inge A. Suhr.

Each Organization with a '*' is a sales agent for ISO publications in
its country. The names of the countries are given in both English and
French (seems to be an old ISO tradition ;-).

  Might prove quite helpful for people trying to understand the
  complexities of internationalization for the first time and
  explains also international and de-facto standards in this area.


  This is an ACM publication about computer related standardization
  issues. The editor-in-chief's address is Carl Cargill, Sun Microsystems,
