24、6 IEC 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-47: Tests Thermal shocks FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization co

25、mprising 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 St

26、andards, 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 pr

27、eparatory 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 org

28、anizations. 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 for

29、m 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 misinterpreta

30、tion 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 re

31、gional 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 ou

32、t 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 Committee

33、s 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) Attention is drawn to the

34、 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

35、responsible for identifying any or all such patent rights. International Standard IEC 61300-2-47 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This fourth edition cancels and replaces the third edition

36、published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: review of temperature limit in the test severity. 4 IEC 61300-2-47:2016 IEC 2016 The text of this standard is based on the followin

37、g documents: CDV Report on voting 86B/3879/CDV 86B/3937A/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. The readers attention

38、is drawn to the fact that Annex A lists an “in some-country” clause on differing practices of a less permanent nature relating to the subject of this standard. A list of all parts in the IEC 61300 series, published under the general title Fibre optic interconnecting devices and passive components Ba

39、sic test and measurement procedures, 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 da

40、te, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 61300-2-47:2016 IEC 2016 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-47: Tests Thermal shocks 1 Scope This part of IEC 61300 details a proc

41、edure for determining the suitability of a fibre optic device to withstand the effects of thermal shock. In practice, this means a very short change over time between extreme temperatures. 2 Normative references The following documents, in whole or in part, are normatively referenced in this documen

42、t 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 60068-2-14, Environmental testing Part 2-14: Tests Test N: Change of temperature IEC 61300-

43、3-1, Fibre optic interconnecting devices and passive components Basic test and measurement procedures Part 3-1: Examinations and measurements Visual examination 3 General description The procedure described in this standard is conducted in accordance with IEC 60068-2-14, test Na. The device under te

44、st (DUT) is first subjected to one extreme of temperature for a given period of time. It is then subjected to the other extreme of temperature for an equal period of time. Two test methods are considered: manual or automatic. Both methods are considered as equivalent. The reference method is the aut

45、omatic one. 4 Apparatus 4.1 Testing chambers a) Two separate chambers or one rapid temperature change rate may be used. If two chambers are used, one for the low temperature and one for the high temperature, they are located such as to allow transfer of the DUT from one chamber to the other within t

46、he prescribed time. Either manual or automatic transfer methods may be used. b) The chambers shall be capable of maintaining the atmosphere at the appropriate temperature for the test in any region where the DUT is placed. c) The absolute humidity of the atmosphere inside the chambers should not exc

47、eed 20 g/m 3 . At the temperature of 60 C and standard air pressure, the relative humidity should be less than 16 %. d) The temperature of the walls of the hot and cold chambers shall not differ by more than 3 % and 8 % respectively from the specified ambient temperature of the test, expressed in Ke

48、lvin (tolerance of 3 % for high temperature, and 8 % for low temperature). 6 IEC 61300-2-47:2016 IEC 2016 e) The volume of the chambers and the air velocity shall be such that after insertion of the DUT, the temperature of the atmosphere shall be within the specified tolerance after a time of not mo

49、re than 10 % of the exposure time. f) The air of the chamber shall be circulated so that the air velocity, measured close to the DUT, shall be not less than 2 m/s. 4.2 Support for mounting the DUT Unless otherwise specified in the relevant specification, the thermal conductivity of the supports for mounting the DUT shall be low, such that for practical purposes the DUT is thermally isolated.
