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 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 of IEC 61300-1:2011 Table below is an adaptation of that table BS EN 61300-3-49:2013 61300-3-49 © IEC:2013 –6– Table – Test conditions 4.1 Temperature T Relative humidity RH 22,0 °C to 24,0 °C (50,0 ± 10,0) % RH Apparatus 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 in the fixture so that the front face of connector housing is retained by the fixture as shown in Figure and Figure 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 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 measurement 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 5.1 Procedure Method A: Method using weight (Figure 1) a) Prepare the DUT according to the manufacturer’s 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 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 s BS EN 61300-3-49:2013 61300-3-49 © IEC:2013 –7– IEC 485/13 Key Fixture DUT (optical connector) Guide pin Guide pin chuck Front face of housing Weight Figure – Method for

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) Connect guide pin chuck 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 force 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 BS EN 61300-3-49:2013 61300-3-49 © IEC:2013 –8– IEC 486/13 Key Fixture DUT (optical connector) Guide pin Guide pin chuck Front face of housing
