28、, 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 to the guide pin chuck. A measurement of gui

29、de 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. BS EN 61300-3-49:2013 6 61300-3-49 IEC:2013 Table 1

30、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 connector shall be placed

31、 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 ideal when using a tens

32、ile 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 measurement is used for pas

33、s/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: Method using weight

34、(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 the total weight of chu

35、ck 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

36、force. Unless otherwise specified, the minimum duration shall be 5 s.

38、huck to tensile testing machine. Ensure that the DUT is fixed vertical and the pulling device is precisely aligned on the axis of guide pin. e) Apply tension using the tensile testing machine. The weight of the guide pin chuck should be factored in. Be sure that the DUT remains vertical and the forc

39、e is applied in the axis of the guide pin. Measure and record the maximum value when the guide pin is withdrawn. The rate of application shall be less than 50 mm/s when the rate is not specified. 2 4 6 3 1 5 IEC 485/13 BS EN 61300-3-49:2013 8 61300-3-49 IEC:2013 Key 1 Fixture 2 DUT (optical connecto
