BR-PV-MBT Module breakage Tester
Implementation of standards:
IEC 61730-2:2004 & Ed.2, AS/NZS 2208:1996, ISO 12543-2:2006, ISO 12543-3:1998...
45.5Kg (IEC 61730:2-2004 & Ed.2)
46.0Kg (AS/NZS 2208:1996)
45.0Kg (ISO 12543-2, ISO 12543-3)
Module fixture: can installat 2×1.35m, 2×1m, 1.58×0.808m, 1.4×1.1m, 1.3×1.1m etc.
The apparatus is as follows:
a) The impactor shall be a bag made of a suitable material and capable to be filled to the required weight using a suitable filling material (e.g. steel balls or pellets). The exterior of the bag shall be wrapped with tape as shown in the figure 4 in order to avoid uneven surfaces like stitching.When filled the length of the impactor shall lie within 300mm to 400mm. The ratio of widest diameter to height shall lie within 1:1.5 to 1:1.4)
b) When filled, the impactor bag shall have dimensions as described in figure 4 and a weight of 45.5kg ±0.5kg. Adhesive tape bag used in diagonal, overlapping manner shall cover the entire surface of bag. Tape neck shall be processed separately.
c) A test frame similar to that shown in Figures 5 and 6 shall be provided to minimize movement and deflection during testing. The structure framing and bracing shall be steel channel (approximately C 100mm, 200mm or larger) and shall have a minimum moment of inertia of approximately 187cm4. The frame shall be welded or securely bolted at the corners to minimize twisting during impact. It shall also be bolted to the floor to prevent movement during impact testing.
The procedure is as follows:
a) At rest the impactor bag shall hang no more than 13mm from the surface of the module sample and no more than 50 mm from the centre of the module sample.
b) Lift the impactor to a drop height of 450mm from the surface of the module sample, allow the impactor to stabilize, and then release it to strike the module sample.
