    18、RCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-55: Tests Strength of mounted adaptor FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Natio

    19、nal 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 Reports, Public

    20、ly 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 non- governm

    21、ental 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 of IEC on

    22、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 accepted

    23、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 international u

    24、niformity, 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 the latter.

    25、 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 users should e

    26、nsure 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 other damage o

    27、f 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. Use of the

    28、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 rights. I

    29、nternational Standard IEC 61300-2-55 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this International Standard is based on the following documents: FDIS Report on voting 86B/4054/FDIS 86B/40

    30、67/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 61300-2-55:2017 IEC 2017 5 A list of all parts in the IEC 613

    31、00 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 document will remain unchanged until the stability date indicated on the

    32、 IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

    37、/www.iso.org/obp 4 General description The device under test (DUT) is an optical connector adaptor or receptacle mounted to a fixture. A force is applied to the adaptor or receptacle at the specified rate until the required load has been reached. 5 Apparatus 5.1 Loading method 5.1.1 General The test

    38、 apparatus shall be capable of applying an axial load to the DUT. Two methods for applying the load are shown in Figure 1 and Figure 2. IEC 61300-2-55:2017 IEC 2017 7 5.1.2 Method A The axial load is applied to the DUT via the force gauge and the holding fixture attached to the DUT as shown in Figur

    39、e 1. Figure 1 Example of test apparatus for method A 5.1.3 Method B The axial load is applied directly to the DUT via the force gauge only, as shown in Figure 2. IEC DUT Fixture Holding fixture Force gauge Direction of force 8 IEC 61300-2-55:2017 IEC 2017 Figure 2 Example of test apparatus for metho

    40、d B 5.2 Force generator The force generator may be any device or apparatus capable of smoothly applying the specified force at the specified rate. 5.3 Force gauge A force gauge of specified uncertainty shall be used to measure the axial force applied to the DUT. 5.4 Holding fixture A suitable holdin

    41、g fixture shall be used in method A to couple the force generator to the DUT. A connector plug may be used as a holding fixture. Care shall be taken in the design and use of the holding fixture to ensure that it does not apply compressive forces which might deform or break the DUT. 5.5 Fixture The f

    42、ixture shall be rigid enough not to bend during the test. The cut-outs for IEC 61754-4 series (SC), IEC 61754-7 series (MPO) and IEC 61754-20 (LC) are given in Annex A. For other connector styles, give the cut-out dimensions and panel thickness dimension as part of the details to be specified (see C

    43、lause 8). 5.6 Timer A device measures the total time the force is applied. IEC DUT Fixture Force gauge Direction of force IEC 61300-2-55:2017 IEC 2017 9 6 Procedure 6.1 General description Unless otherwise specified, the test shall be performed under standard test conditions and the DUT shall be sub

    44、jected to the test procedure according to 6.2 to 6.7. 6.2 Pre-conditioning Unless otherwise specified, pre-condition each DUT for more than or equal to 2 h at the standard atmospheric conditions specified in IEC 61300-1. 6.3 Initial examination and measurement Initial examinations and measurements o

    45、n the DUT shall be made as required by the relevant specification. Visual examination shall be done according to IEC 61300-3-1. 6.4 Mount DUT Securely mount the DUT to the apparatus as shown in Figure 1 or Figure 2. 6.5 Conditioning Smoothly apply the force at the specified rate up to the specified

    46、value and hold for the specified duration according to the relevant specification. When the relevant specification does not define a force value, refer to the recommended severities shown in Table 1. Standard atmospheric conditions to be as specified in IEC 61300-1. 6.6 Recovery Remove the DUT from

    47、the test apparatus and allow the DUT to recover under standard conditions for 10 min, as defined in IEC 61300-1, unless otherwise specified in the relevant specification. 6.7 Final examination and measurement Unless otherwise specified, visually examine the DUT and its component parts in accordance

    48、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. 7 Severity The severity of the test is dependent upon the magnitude of the force and to a lesse

    49、r extent to the rate of application and duration at the specified load. The magnitude, rate of application and duration at the specified load shall be given in the relevant specification. Recommended values of the test parameters are given in Table 1.
