29、thick steel plate large enough for the whole DUT or as specified in the relevant specification. The plate is place on a non yielding surface. The plate has rounded edges. BS EN 61300-2-10:2012 6 61300-2-10 IEC:2012 4.3 Pad A 10 mm thick steel pad, size as Table 1, or as specified in the relevant spe
30、cification, bonded to a non-yielding plate. The pad has rounded edges. 4.4 Force generator The force generator may be any device or apparatus capable of smoothly applying the specified load at the specified rate. 4.5 Gauge A suitable instrument for measuring the load applied to the DUT.

Unless otherwise specified, the DUT shall be subjected to the crush resistance test in a non-operational mode. Clean the optical and
32、 mechanical parts of the DUT according to the manufacturers instructions. 5.2 Pre-conditioning Unless otherwise specified, pre-condition each prepared closure DUT for 4 h and each prepared connector DUT for 2 h at the standard test conditions specified in IEC 61300-1. 5.3 Initial measurements The DU
33、T shall be visually inspected, optically measured and mechanically checked as required by the relevant specification. 4 1 3 2 IEC 1602/12 BS EN 61300-2-10:201261300-2-10 IEC:2012 7 5.4 Device mounting Position the DUT centrally on the test surface contained in the shallow box. 5.5 Conditioning a) Pl
34、ace the pad over the DUT. b) Smoothly apply the specified load to the pad. c) Maintain the load for the specified duration. 5.6 Final examinations and measurements Upon completion of the test, the DUT shall be examined and all necessary observations recorded as specified in the relevant specificatio
35、n. Careful attention shall be given to the loss of optical continuity (where tested, use IEC 61300-3-4 and IEC 61300-3-6), broken parts (IEC 61300-3-1), and damage to seals (IEC 61300-2-38). 6 Severity The severity consists of the combination of the load, load area and the duration.
