Optical fibres - Part 1-1: Measurement methods and test procedures - General and guidance
IEC 60793-1-1: 2017 lists and gives guidance on the use of documents giving the uniform requirements for measuring and testing optical fibres, thereby assisting in the inspection of fibres and cables for commercial (mostly telecommunications) purposes. The individual measurement and test methods are contained in the different parts of the IEC 60793 series. They are identified as IEC 60793-1-X, where "X" is an assigned sub-part number, indicating its affiliation to the IEC 60793-1 series. In general, measurements and tests methods apply to all class A multimode fibres and class B and class C single-mode optical fibres covered by IEC 60793-2 (all parts) relating to product specifications, although there can be exceptions. Clause 1 of each part of the IEC 60793 series contains the scope for each particular attribute. This fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: addition of rounding rules in Clause REF _Ref469662545 \r \h 4 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003400360039003600360032003500340035000000 ; addition of two packaging requirements in Clause REF _Ref469662553 \r \h 10 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003400360039003600360032003500350033000000 d) and e).
Fibres optiques - Partie 1-1 : Méthodes de mesure et procédures d’essai - Généralités et recommandations
IEC 60793-1-1:2017 donne la liste, et les recommandations relatives à l'utilisation, des documents qui fournissent les exigences uniformes pour les mesurages et les essais des fibres optiques, permettant ainsi le contrôle des fibres et des câbles proposés sur le marché (le plus souvent dans le domaine des télécommunications). Les méthodes d'essai et de mesure individuelles sont contenues dans les différentes parties de la série IEC 60793. Elles sont identifiées IEC 60793-1-X, où "X" est le numéro assigné à une sous-partie, indiquant qu'elle appartient à la série IEC 60793-1. En général, les méthodes d’essai et de mesure s’appliquent à toutes les fibres multimodales de la classe A et à toutes les fibres unimodales de la classe B et de la classe C couvertes par l’IEC 60793-2 (toutes les parties) qui traite des spécifications de produits, bien qu’il puisse exister des exceptions. L’Article 1 de chaque partie de la série IEC 60793 contient le domaine d’application pour chaque attribut particulier. Cette quatrième édition annule et remplace la troisième édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: ajout de règles d’arrondissage dans l’Article 4; ajout de deux exigences relatives à l’emballage dans l’Article 10 d) et e).
La présente version bilingue (2020-09) correspond à la version anglaise monolingue publiée en 2017-01.

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

International Standard IEC 60793-1-1 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This fourth edition cancels and replaces the third edition published in 2008. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) addition of rounding rules in Clause 4;
b) addition of two packaging requirements in Clause 10 d) and e).

INTRODUCTION
Publications in the IEC 60793-1 series concern measurement methods and test procedures as
they apply to optical fibres.
Within the same series, several different areas are grouped, as follows:
Parts 1-10 to 1-19: General
Parts 1-20 to 1-29: Measurement methods and test procedures for dimensions
Parts 1-30 to 1-39: Measurement methods and test procedures for mechanical
characteristics
Parts 1-40 to 1-49: Measurement methods and test procedures for transmission and optical
characteristics
Parts 1-50 to 1-59: Measurement methods and test procedures for environmental
characteristics.

OPTICAL FIBRES –
Part 1-1: Measurement methods and test procedures –
General and guidance
1 Scope
This part of IEC 60793 lists and gives guidance on the use of documents giving the uniform
requirements for measuring and testing optical fibres, thereby assisting in the inspection of
fibres and cables for commercial (mostly telecommunications) purposes.
The individual measurement and test methods are contained in the different parts of the
IEC 60793 series. They are identified as IEC 60793-1-X, where "X" is an assigned sub-part
number, indicating its affiliation to the IEC 60793-1 series.
In general, measurements and tests methods apply to all class A multimode fibres and class B
and class C single-mode optical fibres covered by IEC 60793-2 (all parts) relating to product
specifications, although there can be exceptions. Clause 1 of each part of the IEC 60793 series
contains the scope for each particular attribute.
