21、sistance 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 international co-operation on all questions concerning standardizati
22、on 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 (hereafter referred to as “IEC Publication(s)”). Their preparation is en
23、trusted 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 participate in this preparation. IEC collaborates closely with the Inte
24、rnational 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, an international consensus of opinion on the relevant subjects since
25、 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 all reasonable efforts are made to ensure that the technical content o
26、f 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 apply IEC Publications transparently to the maximum extent possible in
27、 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 conformity. Independent certification bodies provide conformity ass
28、essment 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 publication. 7) No liability shall attach to IEC or its directors, emp
29、loyees, 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 indirect, or for costs (including legal fees) and expenses arising out of t
30、he 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 correct application of this publication. 9) Attention is drawn to the
31、 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 61300-2-10 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and pa
32、ssive components, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 1995. It constitutes a technical revision. The changes with respect to the previous edition are to reconsider the entire text. 4 61300-2-10 IEC:2012 The text of this
33、 standard is based on the following documents: FDIS Report on voting 86B/3439/FDIS 86B/3484/RVD 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 Directi
34、ves, Part 2. A list of all parts of IEC 61300 series, published under the general title, Fibre optic interconnecting devices 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 unch
35、anged 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. 61300-2-10 IEC:2012 5 FIBRE OPTIC INTERCONNECTING DEVIC

41、sive load which is applied by a pad. 4 Apparatus 4.1 General The apparatus consists of the following elements (Figure 1). 4.2 Plate A 10 mm thick steel plate large enough for the whole DUT or as specified in the relevant specification. The plate is place on a non yielding surface. The plate has roun
42、ded edges. 6 61300-2-10 IEC:2012 4.3 Pad A 10 mm thick steel pad, size as Table 1, or as specified in the relevant specification, bonded to a non-yielding plate. The pad has rounded edges. 4.4 Force generator The force generator may be any device or apparatus capable of smoothly applying the specifi
43、ed load at the specified rate. 4.5 Gauge A suitable instrument for measuring the load applied to the DUT. Key 1 force generator and gauge 2 pad 3 device under test 4 plate Figure 1 Apparatus 5 Procedure 5.1 DUT preparation Prepare the DUT in accordance with the relevant specification. Unless otherwi
44、se specified, the DUT shall be subjected to the crush resistance test in a non-operational mode. Clean the optical and mechanical parts of the DUT according to the manufacturers instructions. 5.2 Pre-conditioning Unless otherwise specified, pre-condition each prepared closure DUT for 4 h and each pr
45、epared connector DUT for 2 h at the standard test conditions specified in IEC 61300-1. 5.3 Initial measurements The DUT shall be visually inspected, optically measured and mechanically checked as required by the relevant specification. 4 1 3 2 IEC 1602/12 61300-2-10 IEC:2012 7 5.4 Device mounting Po

47、all be examined and all necessary observations recorded as specified in the relevant specification. Careful attention shall be given to the loss of optical continuity (where tested, use IEC 61300-3-4 and IEC 61300-3-6), broken parts (IEC 61300-3-1), and damage to seals (IEC 61300-2-38). 6 Severity T
