Optical fibres - Part 1-1: Measurement methods and test procedures - General and guidance

NEW!IEC 60793-1-1:2017 is available as IEC 60793-1-1:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
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).

Optična vlakna - 1-1. del: Metode merjenja in preskusni postopki - Splošno in smernice (IEC 60793-1-1:2017)

Ta del standarda IEC 60793 navaja dokumente, ki podajajo enotne zahteve za merjenje in preskušanje optičnih vlaken, ter podaja navodila o njihovi uporabi, s čimer je v pomoč pri pregledovanju vlaken in kablov za komercialne (večinoma telekomunikacijske) namene.
Posamezne merilne in preskusne metode so navedene v različnih delih skupine standardov IEC 60793. Določene so kot IEC 60793-1-X, pri čemer je »X« dodeljena številka poddela, ki označuje njegovo zvezo s skupino standardov IEC 60793-1.
Na splošno se merilne in preskusne metode uporabljajo za vsa večrodna vlakna razreda A ter enorodna optična vlakna razreda B in C, ki so zajeta v standardu IEC 60793-2 (vsi deli) v zvezi s specifikacijami izdelkov, čeprav lahko obstajajo izjeme. Točka 1 vsakega dela skupine standardov IEC 60793 vsebuje področje uporabe za posamezen atribut.

General and guidance
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
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
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
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.
