22、1300-2-7 IEC:2013 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-7: Tests Bending moment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat
23、ion comprising 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 Internatio
24、nal Standards, 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 t
25、his preparatory 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 tw
26、o 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 each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have th
27、e 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 of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinter
28、pretation 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
29、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 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carri
30、ed 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, employees, servants or agents including individual experts and members of its technical committees and IEC National Comm
31、ittees 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 t
32、o 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 possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be
33、held responsible for identifying any or all such patent rights. International Standard IEC 61300-2-7 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edit
34、ion published in 1995. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) a complete reconsideration of the entire document, including additional normative references; b) clarification of the device under te
35、st (DUT); c) clarification of the relationship between severities, performance categories and the DUT. 4 61300-2-7 IEC:2013 The text of this standard is based on the following documents: FDIS Report on voting 86B/3579A/FDIS 86B/3621/RVD Full information on the voting for the approval of this standar
36、d 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 IEC 61300 series, published under the general title Fibre optic interconnecting and passive components Basic test and measu
37、rement 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 date, the publicatio
38、n will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61300-2-7 IEC:2013 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-7: Tests Bending moment 1 Scope This part of IEC 61300 details a procedure for determining the sui
39、tability of a fibre optic device to withstand the environmental condition of a bending moment which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of a bending moment. The bending moment may result in effects that would destroy
40、functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties may also occur. The specimen may be a component, a connector set, a splice or other device combination intended for fibre optic usage. 2 Normative refere
41、nces The following documents, 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. IE

44、paratus and subjected to a bending moment which is maintained at a given temperature for a specified duration, as specified in the relevant specification. The bending moment is smoothly applied to the specimen so as to bend its longitudinal axis. 4 Apparatus 4.1 Design for a 1 piece or 3 piece DUT T
45、his design is suitable for specimens which consist of one part, like splices. The apparatus consists of the following elements: a) two steel rods placed at an appropriate distance in from the extreme ends of the DUT; 6 61300-2-7 IEC:2013 b) a steel finger with a defined endface radius which is place
46、d in the middle of the supported DUT; c) a force generator capable of smoothly applying the specified force at the specified rate to the steel finger; d) an optional clamping device to fix the DUT; e) additional measuring equipment. If the specimen has to operate during the test, then additional equ
47、ipment and operating conditions shall be specified in the relevant specification. An example of an apparatus is shown in Figure 1. Rigid plateCBAForce FDDUTFigure 1 Test apparatus to apply a bending moment to a 1 piece or 3 piece DUT 4.2 Design for a 2 piece DUT This design is suitable for specimens
48、 which consist of two parts, like connector sets. The two parts are joined together. The apparatus consists of the following elements: a) a clamping device on which the DUT, Part 1 is placed; b) a steel finger with a defined endface radius which is placed at the end of the DUT, Part 2; c) a force ge
49、nerator capable of smoothly applying the specified force at the specified rate to the steel finger; d) additional measuring equipment. If the specimen has to operate during the test, then additional equipment and operating conditions shall be specified in the relevant specification. An example of an apparatus is shown in Figure 2.
