24、-50: Measurement methods and test procedures Damp heat (steady state) tests FOREWORD 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 i

25、nternational 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 (here

26、after 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 par

27、ticipate 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,

28、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 al

29、l 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 ap

30、ply 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

31、 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 pu

32、blication. 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 indirec

33、t, 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) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the c

34、orrect 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 60793-1-50 has been prep

35、ared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. 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 previou

36、s edition: harmonization of the content with sectional specifications of relevant fibre types; extension of the applicability of the standard to class C single-mode fibres. 4 IEC 60793-1-50:2014 IEC 2014 The text of this standard is based on the following documents: CDV Report on voting 86A/1526/CDV

37、 86A/1572/RVC Full information on the voting for the approval of this standard can be found in the report 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 gene

38、ral title Optical fibres, can be found on the IEC website. The committee has decided that the contents 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 pub

39、lication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover 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

40、this document using a colour printer. IEC 60793-1-50:2014 IEC 2014 5 OPTICAL FIBRES Part 1-50: Measurement methods and test procedures Damp heat (steady state) tests 1 Scope This part of IEC 60793 provides a practical method for evaluating fibre performance in a defined environment. The purpose of t

41、his standard is to determine the suitability of optical fibre sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and/or transport. The test is primarily in

42、tended to permit the observation of effects of high humidity at constant temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-78, Test Cab. NOTE The applicability of this test to other fibre categories is under study. 2 Normative references The following docume

43、nts, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60068-2-78, Environment

47、sists of an environmental chamber in accordance with IEC 60068-2-78, Test Cab. The chamber shall be capable of housing the specimen and of allowing access for measurement during conditioning. It shall also be capable of maintaining the specified temperature and humidity within the specified toleranc

48、es. Forced air circulation may be used to maintain homogeneous conditions. The chamber and accessories shall be constructed and arranged in such a manner as to avoid condensation dripping on the specimen. 3.2 Humidifier De-mineralized or de-ionized water is used to obtain the specified humidity. No

49、rust or corrosion contaminants shall be imposed on the specimen by the test facility. The water added to the humidifier shall be controlled according to the manufacturers instructions. 3.3 Other apparatus Additional apparatus may be necessary to perform the examinations and measurements (or as specified in the detail specification). 4 Sampling and specimens For optical measurements, the
