20、CAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-17: Tests Cold FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees
21、(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 Standards, Technical Specifications, Technical Repor
22、ts, 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 preparatory work. International, governmental and no
23、n- 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 organizations. 2) The formal decisions or agreements
24、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 form of recommendations for international use and are
25、 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 misinterpretation by any end user. 4) In order to promote inter
26、national 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 regional publication shall be clearly indicated in t
27、he 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 out by independent certification bodies. 6) All user
28、s 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 Committees for any personal injury, property damage or othe
29、r 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 Normative references cited in this publication. U
30、se 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 responsible for identifying any or all such patent
31、 rights. International Standard IEC 61300-2-17 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2003. This edition constitutes a tech
32、nical revision. The main changes with respect to the previous edition are listed below: a) Procedure and details to be specified were reconsidered. b) The deviation of the temperature in severity was changed 3 C to 2 C. 4 61300-2-17 IEC:2010 The text of this standard is based on the following docume
33、nts: CDV Report on voting 86B/2984/CDV 86B/3089/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 list of all parts in the IE
34、C 61300 series, published under the general title, Fibre optic interconnecting and passive components Basic 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 th
35、e 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. 61300-2-17 IEC:2010 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASU
36、REMENT PROCEDURES Part 2-17: Tests Cold 1 Scope This part of IEC 61300 details a procedure for determining the suitability of a fibre optic device to withstand environmental conditions of extended low temperature (cold), which may occur in use, storage and/or transport. This procedure does not asses
37、s the ability of a device to operate during temperature variations; in this case, IEC 61300-2-22 would be used. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated referenc
38、es, the latest edition of the referenced document (including any amendments) applies.

39、-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 This procedure is conducted in accordance with IEC 60068-2-1, test Ab. The Device Under Test (DUT) is placed in a ch
40、amber at ambient temperature. The temperature is then lowered to test temperature at a rate not exceeding 1 C/min averaged over a maximum period of 5 min, and maintained at that temperature for the specified duration. The chamber temperature is then raised to ambient and the DUT is allowed to attain
41、 ambient temperature before final measurements are made. 4 Apparatus 4.1 Chamber The apparatus is an environmental chamber in accordance with IEC 60068-2-1, test Ab. The chamber shall be capable of housing the DUT and of allowing access for measurement during conditioning, if required. It shall also
42、 be capable of maintaining the specified temperature and tolerance. Forced air circulation may be used to maintain homogeneous conditions. Care shall be taken to ensure that the DUT is not directly exposed to the heating or cooling elements. 4.2 Other apparatus Additional apparatus may be necessary
43、to perform the measurements specified by the relevant specification. 6 61300-2-17 IEC:2010 4.3 Support for mounting the DUT Unless otherwise specified in the relevant specifications, the thermal conductivity of the supports for mounting the DUT shall be low, such that for practical purposes the DUT
44、is thermally isolated. 5 Procedure 5.1 General Conduct the test according to the following procedure. Unless otherwise specified in the relevant specification, the following applies: if the component construction includes optical leads, include 1,5 m of cable in the environmental chamber for each po
45、rt 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 1 h. 5.2 Preconditioning Unless otherwise stated in the relevant specification, maintain the DUT under standard atmospheri
46、c conditions specified in IEC 61300-1 for a minimum of 2 h. Clean the mechanical and optical alignment parts of the DUT according to the manufacturers instructions. 5.3 Initial measurements Complete initial examinations and measurements as required by the relevant specification. 5.4 Testing a) Place
47、 the DUT in the chamber in its normal operating position and make connections to the monitoring equipment. b) Adjust the chamber temperature to the specified severity. The rate of change of temperature shall not exceed 1 C/min, averaged over a maximum period of 5 min. Allow the DUT to reach temperat
48、ure stability. The relevant specification may call for measurements to be made during the test and will give details of how this should be done. c) On completion of the test, allow the DUT to remain in the chamber while the temperature is gradually raised to standard atmospheric conditions. The rate
49、 of change of temperature shall not exceed 1 C/min, averaged over a maximum period of 5 min. 5.5 Recovery Dry the DUT if necessary and allow it to remain under standard atmospheric conditions for a period of 2 h. 5.6 Final measurements On completion of the test, remove all fixtures. Clean the mechanical and optical alignment parts of the DUT according to the manufacturers instruc
