coupling mechanism is involved, each cycle of engagement shall be conducted with all other mechanisms properly engaged.4apparatusthe apparatus shall include the following elements:4.1fixturingthe device should be tested under normal conditions of use. w here appropriate, suitable clamps, jaws or other means may be used to hold the mating parts of the device in proper alignment during the test.4.2force applicatoruse a means of applying the force or torque to engage and separate the specimen. unless otherwise stated, the force to engage the device shall be applied manually. w here required, a means of applying the engagement force or torque shall be specified.bs en 61300-2-2:200861300-2-2 iec:2008 7 4.3measuring equipmentunless otherwise specified, measuring equipment specified in iec 61300-3-4 shall be connected to the dut for monitoring the optical performance during the test.5procedure5.1initial inspectioncomplete initial examinations and measurements of the specimen as specified in the relevant specification.5.2cyclingunless otherwise specified in the relevant specification, a cycle shall consist of one normal full engagement and separation of the coupling mechanism to be evaluated. the minimum time between each engagement shall be 3 s.w hen the specimen involves more than one coupling mechanism, the cycles shall be conducted with all mechanisms properly engaged. the mating shall be accomplished according to the manufacturers instructions. in the case of a plug-adapter-plug configuration, only one plug is subjected to successive engagement and separations

described in iec 61300-3-3, unless otherwise specified in the relevant specification. the results shall be within the limit given in the specification.choose one of the measurement conditions below.5.3.2measurement condition ameasurements are recorded after every mating. if the value of attenuation or return loss exceeds the specified limit, the measurement should be recorded. the connector may then be cleaned according to the manufacturers instructions and the test resumed. the cleaning of the connector shall be recorded.the number of cleaning operations shall be limited to 20 (4 % of matings).5.3.3measurement condition bthe sample population is divided as equally as possible into three specimen groups. each group is mounted in a holding fixture (e.g. adapter panel) at the following distances from the floor: 0,9 m, 1,4 m and 1,8 m.for each connector pair, perform an initial cleaning and record baseline optical measurements (e.g. attenuation, return loss). for each connector pair, perform optical measurements on every 25th mating. clean only the cycled connector prior to every 25th mating. clean both connectors prior to every 50th mating. the following sequence is an example:0-1cleaning (both sides)1-1engagement1-2separation2-1engagement2-2separation.24-1engagement24-2separation24-3cleaning (cycled plug
