28、Part 3-28: Examinations and measurements Transient loss 3 General description This procedure is derived from IEC 60068-2-6, test Fc. The device under test (DUT) is mounted on a vibration generator and vibrated with a sinusoidal motion. The DUT is exposed to vibration in three mutually perpendicular
29、directions, one of which is parallel to the optical axis. The vibration amplitude is specified either in terms of constant displacement or constant acceleration. 4 Apparatus 4.1 General The apparatus shall be in accordance with IEC 60068-2-6, test Fc and consists of the following elements. BS EN 613
30、00-2-1:2009IEC 61300-2-1:2009 6 4.2 Vibration generator A vibration generator capable of generating a sinusoidal excitation and its auxiliary test equipment. 4.3 Mounting fixture A suitable DUT mounting fixture capable of transmitting the vibration conditions specified shall be used. The mounting fi
31、xture shall be designed so that the resonant vibration inherent in the fixture shall not have an effect on the specified frequency range. The amplitude and the acceleration of the applied vibration shall be monitored on the test fixture near the DUT mounting points. 4.4 Measuring equipment Unless ot
32、herwise specified, measuring equipment specified in IEC 61300-3-3 shall be connected to the DUT for monitoring the optical performances during the test; moreover the transient loss measuring equipment specified in IEC 61300-3-28 shall be used to detect fast variation of attenuation. 5 Procedure 5.1
33、Preparation of DUT Prepare the DUT according to the manufacturers instructions or as specified in the relevant specification. 5.2 Pre-conditioning Pre-condition the DUT for 2 h at the standard test conditions specified in IEC 61300-1, unless otherwise specified in the relevant specification. 5.3 Ini
34、tial measurement Complete initial examinations and measurements of the DUT as required by the relevant specification. 5.4 Conditioning The DUT shall be mounted rigidly to the fixture in a manner that simulates normal mounting as closely as possible. A minimum of 200 mm of optical fibre/cable shall b
35、e unsupported on both ends of the DUT and be attached free of tension to the vibrating surface. Conduct the procedure in accordance with IEC 60068-2-6, test Fc. The DUT shall be vibrated in three mutually perpendicular axes coincident with the principal axes of the device. If the sample has axial sy
36、mmetry the number of axes to be tested can be reduced to two. The vibration endurance shall be performed by sweeping continuously between minimum and maximum frequency at a specified rate. An example of vibration apparatus test is outlined in Figure 1. 5.5 Monitoring The attenuation and/or return lo
37、ss of the DUT shall be monitored during the test using an x-y-plotter, an oscilloscope or/and a digital data acquisition system for recording as described in IEC 61300-3-28, unless otherwise specified in the relevant specification. Any change in optical performance shall be within the limit given in
38、 the relevant specification.

39、Allow the DUT to remain under standard test conditions for 2 h, as defined in IEC 61300-1, unless otherwise specified in the relevant specification. Clean the DUT in accordance with the manufacturers instructions. 5.7 Final measurements On completion of the test, remove all fixtures and make final m
40、easurements, as defined by the relevant specification, to ensure that there is no permanent damage to the DUT. The results of the final measurement shall be within the limit established in the relevant specification. Unless otherwise specified, visually examine the DUT in accordance with IEC 61300-3
41、-1. Check for evidence of any degradation in the DUT. This may include, for example: broken, loose or damaged parts or accessories; breaking or damage to the cable jacket, seals, strain relief, or fibres; displaced, bent, broken or chipped parts. 6 Severity The severity consists of the combination o
42、f frequency range, vibration amplitude, sweep rate and either number of sweeps or endurance duration per axis. The severity shall be specified in the relevant specification. Recommended values of the test parameters are given below in Table 1 and 2. BS EN 61300-2-1:2009IEC 61300-2-1:2009 8 7 Details
43、 to be specified The following details, as applicable, shall be specified in the relevant specification: frequency range; vibration amplitude; number of sweeps; endurance duration per axis; frequency change at constant rate; initial examinations and measurements and performance requirements; examina
44、tions and measurements during test and performance requirements; final examinations and measurements and performance requirements; deviations from test procedure; additional pass/fail criteria. _ BS EN 61300-2-1:2009Table 1 Connectors and passive components Category Parameter Value Frequency range 1
