24、D 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 electr
25、ical 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 techn
26、ical 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 Organ
27、ization 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
28、 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 Publicati
29、ons 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
30、 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 service
31、s 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, servant
32、s 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,
33、 use of, or reliance upon, this IEC Publication or any other IEC Publications. 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 th
34、at 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 60793-1-53 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre o
35、ptics. This second edition cancels and replaces the first edition, published in 2001, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: harmonizing the content with sectional specifications of relevant fibre
36、types; extending the applicability of the standard to Class C single-mode fibres. 4 60793-1-53 IEC:2014 The text of this standard is based on the following documents: CDV Report on voting 86A/1529CDV 86A/1575/RVC Full information on the voting for the approval of this standard can be found in the re
37、port on voting indicated in the above table. This publication has been drafted in accordance 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 content
38、s of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60793-1-53 IEC:20
39、14 5 OPTICAL FIBRES Part 1-53: Measurement methods and test procedures Water immersion tests 1 Scope This part of IEC 60793 provides a practical method for evaluating fibre performance in a defined environment. The purpose of this standard is to define a test that determines the suitability of sub-c
40、ategory A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of immersion in distilled or demineralized water which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of immersion
41、 in water over a given period. This procedure is conducted in accordance with IEC 60068-2-18, Test R. NOTE The applicability of this test to other fibre categories is under study. 2 Normative references The following referenced documents are indispensable for the application of this document. For da
42、ted references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Use distilled, demineraliz
45、ed or de- ionized water which has a pH of between 5,0 and 8,0. 3.2 Other apparatus Additional apparatus may be necessary to perform the examinations and measurements (or as specified in the detail specification). 6 60793-1-53 IEC:2014 4 Sampling and specimens To ensure the required repeatability on
46、optical measurements, the length of the specimen shall be at least 1 000 m for fibre sub-categories A1a to A1d, and at least 2 000 m for fibre class B and C. The amount of the specimen outside of the tank shall be minimized and, if it exceeds 10 % of the overall specimen length, this should be repor
47、ted. The preparation of the specimen shall have no detrimental effect on the fibre whilst under test conditions. Unless otherwise specified, the fibre sample should be loosely coiled and that the fibre ends are kept out of the water. The specimen may be coiled horizontally or vertically, with a mini
48、mum bend diameter of 150 mm to avoid any macrobend effects. A length of the control specimen shall be removed prior to the test to enable the completion of required mechanical measurements for comparison to measurements made after the test. 5 Procedure 5.1 General The specimen is placed in a tank wh
49、ich is filled with water held at 23 C 5 C, and held there for 30 days. The attenuation and coating strip force of the specimen are then monitored. Conduct the procedure in accordance with IEC 60068-2-18, Test R, with the “head of water” being not applicable (the head of water is used to test for “water tightness” of electrotechnical products, but it is not required in this application). 5.2 Me
