Structure of the catalogue [back
This part of the Web site provides the organization's catalogue
The catalogue is composed of the following sections:
(provides bibliographic information on standards and standards-type
(provides bibliographic information on publications other than standards
and standards-type documents)
(provides information on withdrawn standards and standards-type
The sections Standards, Other publications and Withdrawn
standards have a navigation bar (red colour) containing links
to the sections Technical committees and Work programme.
This makes it easy to navigate from the catalogue to the standards
development sections and back. The bar also contains a link to a
search form providing possibilities for retrieval of information
on standards and standards-type documents. The Help link
of the bar is linked to the current page.
Standards section [back to
In the Standards section, all standards-type documents, such
as guides, international standardized profiles, recommendations,
technical reports, technical trends assessments, etc., are classified
into fields, groups and sub-groups according to the International
Classification for Standards (ICS). The ICS is a hierarchical classification
which consists of three levels. Level 1 covers broad fields of activity
in standardization. Each field contains a two-digit notation:
e.g. 11 HEALTH CARE TECHNOLOGY
The fields are subdivided into groups (level 2). The notation for
a group consists of the field notation and a three-digit group number
separated by a point:
e.g. 11.040 Medical equipment
A number of groups are further divided into sub-groups (level 3).
The notation of a sub-group consists of the group notation and a
two-digit number separated by a point:
e.g. 11.040.30 Surgical instruments and materials
The same standard may be classified in several groups and/or sub-groups.
If a standard completely covers the subject of a group which is
subdivided into sub-groups, this standard is classified under the
sub-group which has the notation terminating with ".01".
A full copy of the ICS is available on the WSSN web site: (http://www.wssn.net/WSSN/RefDocs/refdocs.html).
The Standards section contains the following bibliographic
information on standards:
a) Reference number - This consists of a prefix, a serial
number and the year of publication. The prefix will usually be "ISO"
to indicate that the publication is an ISO International Standard.
The prefix ISO/IEC denotes a joint ISO and IEC (International
Electrotechnical Commission) publication. ISO/IEC International
Standards are most often developed by Joint ISO/IEC Technical Committee
JTC 1. IEC International Standards with the prefix IEC, but which
carry both the ISO and IEC logos, are also included in the
catalogue. Such standards either belong to JTC 1, or have been developed
in close cooperation with an ISO committee. Similarly to the ISO/IEC
prefix, the ISO/CIE prefix denotes a joint ISO and
CEI (International Commission on Illumination) International Standard.
The prefix may also contain an indication of the type of document:
Amd. denotes an Amendment - a normative document,
developed according to consensus procedures, approved according
to the procedures relevant to the document being amended, and which
changes the technical normative elements of that document.
Cor. denotes a Technical corrigendum - a document
issued to correct a technical error or ambiguity in a normative
document or to correct information that has become outdated, provided
the modification has no effect on the technical normative elements
of the document it corrects.
Guide - either a document dealing with non-normative matters
relating to international standardization, for example the application
of "horizontal" standards; or a normative document developed by
a structure other than a TC/SC, e.g. a policy development committee.
ISP denotes an International Standardized Profile
- an internally agreed, harmonized document which identifies a standard
or group of standards, together with options and parameters, necessary
to perform a function or set of functions.
ITA denotes an Industry Technical Agreement - a
technical document developed by a workshop outside the technical
structures of ISO and IEC.
PAS denotes a Publicly Available Specification
- a normative document, representing a consensus between experts,
approved by a simple majority of the P-members of a TC or SC, and
published to respond to an urgent market need for such a normative
document. Note that a PAS may not conflict with an existing International
Standard, but competing PAS on the same subject are permitted.
R denotes a Recommendation. This designation was
used up to 1972, when ISO began to publish International Standards.
Since then, as they have been revised, ISO recommendations have
gradually been republished as International Standards. A limited
number of ISO recommendations still remain valid and available.
TR denotes a Technical Report - an informative
document containing information of a different kind (e.g. collection
of data) from that normally published in an International Standard.
TTA denotes a Technology Trends Assessment - a
document published to respond to the need for global collaboration
on standardization questions during the early stages of technical
innovation and which gives the state of the art or trend in emerging
fields. TTAs are typically the result of prestandardization work
TS denotes a Technical Specification - a normative
document, developed according to consensus procedures and approved
by two-thirds of the P-members of the responsible committee, which
is published either when the required support cannot be obtained
for the publication of an International Standard or when the subject
is still under technical development, or where for any other reason
there is the future, but no immediate, possibility of agreement
on an International Standard. Note that a TS may not conflict with
an existing International Standard, but competing TS on the same
subject are permitted.
The prefix is followed by a serial number which may include a part
number, separated by a hyphen from the main number. The serial number
is followed by the year of publication separated from the serial
number by a colon.
b) Title of the standard
c) Title of a specific part of the standard
d) Edition - ISO standards are reviewed at maximum intervals
of five years by the relevant technical committee, to determine
whether they should be confirmed, revised or withdrawn. The publication
dates indicated in this Catalogue are those of the latest edition,
which may be an original or a revised standard. The ISO standards
included in the list of standards classified by subject are valid.
If a standard has not re-entered a review cycle, then the latest
date of confirmation may be seen from the stage code, i.e. Stage
code 90.93 (International Standard confirmed); the Stage
date gives the date when the stage was reached, i.e., in this
case, when the standard was confirmed.
e) Languages - The official languages of ISO are English,
French and Russian. ISO International Standards and standards-type
documents are usually published by the Central Secretariat in separate
English and French editions. Certain standards, especially in the
field of terminology, are published in bilingual (English, French)
or trilingual (English, French, Russian) editions. Standards in
certain fields, most notably in the field of information technology,
are frequently published in English only. The ISO Members may publish
ISO standards in other languages.
NOTE: Bilingual and trilingual editions may additionally include
one or more non-official languages.
f) Number of pages of the standard
g) Price code - information on price codes is given below
in How to order standards and
NOTE - Technical corrigenda to standards are free of charge
and are marked with an asterisk (*) in place of a price code.
h) Technical committee/subcommittee - refers to the technical
committee and subcommittee responsible for the development and maintenance
of the standard.
i) ICS - the ICS (International Classification for Standards)
notation of the group or sub-group in which a given standard is
classified. If a standard is classified in several groups and/or
sub-groups, the notations of all these groups and/or sub-groups,
separated by a semicolon, are presented.
j) Publication date - refers to the date when the
document was published either electronically or in a hardcopy form.
