21、ASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-11: Tests Axial compression 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
22、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 Specifications (PAS) a
23、nd 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 organizations liaising with th
24、e 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 express, as nearly
25、 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 Committees in that s
26、ense. 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 National Committees u
27、ndertake 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 does not provide any
28、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 have the latest edit
29、ion 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 whatsoever, whether dir
30、ect 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 publications is indispens
31、able 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 Standard IEC 61300-2-11
32、 has been prepared by subcommittee SC 86B: Fibre optic interconnecting devices and passive 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 previ
33、ous edition are as follows: a) the procedure and details to be specified have been reconsidered; b) the severity of the test has been modified according to the cable diameter; c) the apparatus and mount for the device under test have been reconsidered in the sense of clamping device placement and th
34、is datum has been indicated in an appropriate figure. 4 61300-2-11 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 86B/3487/FDIS 86B/3532/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated
35、in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 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
36、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
37、laced by a revised edition, or amended. 61300-2-11 IEC:2012 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-11: Tests Axial compression 1 Scope The purpose of this part of IEC 61300 is to ensure that the captivation or the attachment of the c
38、able to the fibre optic devices such as fibre optic closures will withstand compressive axial loads likely to be applied during normal service. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
39、For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

40、EC 61300-3-1, Fibre optic interconnecting devices and passive components Basic test and measurement procedures Part 3-1: Examinations and measurements Visual examination 3 General description The specimen is rigidly clamped and an axial compressive load is applied to the cable. 4 Apparatus 4.1 Gener
41、al The test apparatus shall be capable of applying an axial compression load between a clamped specimen and a cable. The apparatus consists of the elements described in 4.2 to 4.5. 4.2 Clamping device A suitable clamping device which grips a length of fibre optic cable over a distance equivalent to
42、at least three times the cable diameter (see Figure 1, Dimension A), and which is capable of providing an axial load without slipping, causing damage to the cable or increasing attenuation. 4.3 Fixed clamping device A fixed clamping device capable of gripping the specimen without altering any of its
43、 mechanical properties. 6 61300-2-11 IEC:2012 4.4 Force generator A force generator may be any device or apparatus capable of smoothly applying the specified force at the specified rate. 4.5 Force gauge A suitable instrument for measuring the applied force being exerted between the specimen and the
44、fibre optic cable. 5 Procedure 5.1 Prepare specimens The specimen shall consist of a fully assembled optical component, prepared in accordance with the relevant specification. Unless otherwise specified, the specimen shall be subjected to the following test procedure in non-operational mode. 5.2 Pre
45、-conditioning Unless otherwise specified, pre-condition each prepared specimen for 2 h at the standard test conditions specified in IEC 61300-1. 5.3 Mount the device under test Securely fix the device under test to the fixed clamping device. See Figure 1 for an example of the test set-up. Clamp the
46、cable at the point of application using a clamping device such that the distance, L, between the rear of the strain relief and the front of the cable clamping device is twice the cable diameter. The length, L, shall be at maximum two times the cable diameter to prevent cable buckling. A L 4 3 5 1 2

Unless otherwise specified, maintain the load for a m
48、inimum of 2 min. The position of the point of application shall be such that the load is axially transmitted. 61300-2-11 IEC:2012 7 5.5 Post-test examination Remove the axial compressive load from the specimen and the specimen from the test mounting. Unless otherwise specified, visually examine the
49、specimen and its component parts in accordance with IEC 61300-3-1. Check for evidence of cracking, permanent deformation or other damage which might impair its function, and against any other pass/fail criteria specified in the relevant specification. Careful attention shall be given to degradation of the optical signal, fibre breakage and excessive movement of the cable relative to the specimen. 6
