20、purpose of this part of IEC 1300 is to measure the forces or torques which are required to fully couple or uncouple an optical connector set. 1.2 General description The connector set components are mounted so that a controlled coupling force or toque can be applied. The force or torque is measured
21、during the entire coupling and/or uncoupling cycle. The procedure is applicable to either twist or push-pull type coupling mechanisms. 2 Apparatus The apparatus shall consist of the following elements. 2.1 Holding fixture(s) The holding fixtures shall be capable of holding the mating components so t
22、hat they do not influence the measured force or torque value. Proper alignment of the mating components shall be maintained throughout the coupling cycle. 2.2 Force or torque generator The force or toque generator shall be capable of smoothly applying the force or toque. 2.3 Force or toque measudng
23、instrument The measuring instrument shall be capable of continuously measuring the force or torque throughout the coupling cycle. 3 Procedure 3.1 Pre-condition the specimen as specified. 3.2 Visually examine the connector set components in the holding fixture(s). 3.3 Position the connector set compo
24、nents in the holding fixture(s). Page 4 EN 61300-3-11 : 1997 3.4 specified, the mating time shall be 3 s minimum. Apply and measure the force or torque to mate the connector set. Unless otherwise 3.5 specified, the unmating time shall be 3 s minimum. Apply and measure the force or torque to unmate t
25、he connector set. Unless otherwise 4 Details to be specified The following details, as applicable, shall be specified in the detail specification: - Preconditioning procedures - Allowable engagement force or torque - Allowable separation force or torque - Deviations from measuring procedure STD BSI
