22、NNECTING 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 comprising all national electrotechnical committees (IEC National Committees).
23、 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 Spe
24、cifications (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 organizatio
25、ns 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
26、 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 C
27、ommittees 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 Na
28、tional 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 do
29、es 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 h
30、ave 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 what
31、soever, 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 Normative references cited in this publication. Use of the referenced public
32、ations 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 Stan
33、dard 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 published in 2010. This edition constitutes a technical revision. This editio
34、n includes the following significant technical change with respect to the previous edition: review of temperature limit in the test severity. BS EN 61300-2-47:2016 4 IEC 61300-2-47:2016 IEC 2016 The text of this standard is based on the following documents: CDV Report on voting 86B/3879/CDV 86B/3937
35、A/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 is drawn to the fact that Annex A lists an “in some-cou
36、ntry” 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 Basic test and measurement procedures, can be found on th
37、e 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 publication will be reconfirmed, withdrawn, rep
38、laced by a revised edition, or amended.

39、ity 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 document and are indispensable for its ap
40、plication. 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 61300-3-1, Fibre optic interconnecting d
41、evices 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 test (DUT) is first subjected to one
42、 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 automatic one. 4 Apparatus 4.1 Testin
43、g 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 the prescribed time. Either manual
44、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 exceed 20 g/m3. At the temperature of
45、 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 Kelvin (tolerance of 3 % for high temp
46、erature, and 8 % for low temperature). BS EN 61300-2-47:2016 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 more than 10 % o
47、f 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 D
48、UT shall be low, such that for practical purposes the DUT is thermally isolated. When testing several DUTs simultaneously, they shall be so placed that free circulation should be provided between DUTs, and between DUTs and chamber surfaces. 5 Procedure 5.1 General Conduct the test according to the f
49、ollowing procedure. If the component construction includes optical leads, include 1,5 m of cable in the climatic chamber for each port monitored during the test. If optical measurements are requested during the test by the relevant specification, these measurements shall be performed at a maximum interval of 10 min during the extreme temperature periods. It is not the intention of the test to record the effects of mechanical movement of the optical cables during the mov
