14、n 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 pu
15、blishes 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 ma
16、y 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 agree
17、ment 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 P
18、ublications 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
19、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 corr
20、esponding 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
21、 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 an
22、d 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 Publications. 8) A
23、ttention 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
24、. 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.
25、 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). 4 IEC 60793-1-1:2017 IEC 2017 The text
26、of this International Standard is based on the following documents: CDV Report on voting 86A/1747/CDV 86A/1774/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accor
27、dance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60793 series, published under the general title Optical fibres, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC
28、website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cov
29、er page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC 60793-1-1:2017 IEC 2017 5 INTRODUCTION Publications in the IEC 60793-1 series concern
30、 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 p
31、rocedures 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. 6 IEC 60793-1-1:2017 IEC 2017 OPTICAL FIBRES Part 1-1: Meas
32、urement 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 telecommu
33、nications) 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 meth
34、ods 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. 2 Norm

46、rom zero“, when the results recorded display more than the significant number of digits required in the acceptance criteria. Only the first digit beyond the number of significant digits is used in determining the rounding. EXAMPLE 1 Against a requirement of 0,22 dB/km maximum attenuation, values up
47、to 0,224 dB/km conform, whilst values of 0,225 dB/km and above are failures. _ 1Please see Annex B, Rule B of ISO 80000-1:2009. 8 IEC 60793-1-1:2017 IEC 2017 EXAMPLE 2 Against a requirement of 0,05 dB, values between 0,054 dB and +0,054 dB are deemed acceptable. EXAMPLE 3 Against a requirement of 0,
48、6 m maximum core concentricity error, values up to 0,64 m are acceptable. 5 Measurement and test categories The categories include a) parameter measurements, b) performance measurements, and c) compliance tests.
