23、lectrotechnical 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 standardization in the electrical and electronic fiel
24、ds. 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 entrusted to technical committees; any IEC
25、 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 International Organization for Standardizati
26、on (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 each technical committee has representa
27、tion 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 of IEC Publications is accurate, IEC cann
28、ot 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 their national and regional publication
29、s. 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 assessment services and, in some areas, acc
30、ess 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, employees, servants or agents including ind
31、ividual 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 the publication, use of, or reliance upon
32、, 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 possibility that some of the elements o
33、f 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 61300-3-49 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical commi
34、ttee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86B/3437/CDV 86B/3497A/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
35、in accordance with the ISO/IEC Directives, Part 2. 4 61300-3-49 IEC:2013 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 the IEC website. The committee ha
36、s 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, replaced by a revised edition, or

42、 optical connectors specified in IEC 61754-7, IEC 61754-10 and IEC 61754-18. This standard describes two methods using weight or a tensile testing machine. The optical connector is held using a fixture. The guide pin is placed in a guide pin chuck. The weight or tensile testing machine is connected
43、to the guide pin chuck. A measurement of guide pin retention force is taken. 3.2 Test conditions For precise measurements such as for design verification, test conditions shall be controlled accurately as required in Table 1 of IEC 61300-1:2011. Table 1 below is an adaptation of that table. 6 61300-
44、3-49 IEC:2013 Table 1 Test conditions Temperature T Relative humidity RH 22,0 C to 24,0 C (50,0 10,0) % RH 4 Apparatus 4.1 Fixture The measurement shall not be affected by the connector fixture. The position and direction of connector during the test shall not change as the test is repeated. The con
45、nector shall be placed in the fixture so that the front face of connector housing is retained by the fixture as shown in Figure 1 and Figure 2. 4.2 Guide pin chuck The guide pin chuck shall have a pin retention force much larger than required connector guide pin retention force. More than 200 N is i
46、deal when using a tensile testing machine. The connection of the guide pin chuck to the weight or tensile testing machine shall not affect the measurement nor divert the applied force from the axis of guide pin. 4.3 Weight The weight to be used depends on the test to be carried out. The weight measu
47、rement is used for pass/fail tests including final inspection. 4.4 Tensile testing machine The tensile testing machine shall be able to record (and/or hold) the maximum value during the measurement. Tensile testing machine measurement is used for design verification testing. 5 Procedure 5.1 Method A
48、: Method using weight (Figure 1) a) Prepare the DUT according to the manufacturers instructions and check the appearance in accordance with IEC 61300-3-1. b) Place the DUT in the fixture and check the appearance. c) Place the guide pin in the chuck. d) Fix the weight to the guide pin chuck. Adjust t
49、he total weight of chuck and weight to the specified value. Ensure the DUT is fixed vertical. e) Apply the weight slowly. Be sure that the DUT remains vertical and the force is applied in the axis of the guide pin. f) Wait for the specified duration. Record whether or not the guide pin remains in place for the specified force. Unless otherwise specified, the minimum duration shall be 5
