Apparatus for Module Breakage Test
Impact Test Frame and Impactor


Module breakage test equipment. 45kg impactor and impact frame 1525 mm*2480 mm. Based on: IEC 61730-2 2016 and ANSI Z97 .1

Purpose
The purpose of this test is to provide confidence that risk of physical injuries can be minimized if the PV module is broken in its specified installation. For building integrated or overhead applications additional tests may be required according to relevant building codes.

NOT E 1 MST 32 is based on ANSI Z97 .1
NOTE 2 It does not cover electric shock, only e.g. piercing cuts and fall -through injuries.

Apparatus
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 (eg steel balls or pellets). The exterior of the bag shall be wrapped with tape as shown in the Figure 5 in order to avoid uneven surfaces like stitching. When filled, the impactor bag shall have dimensions as described in Figure 5 and a weight of 45,5 kg + 0,5 kg. The ratio of widest diameter to height shall
be between 1:1.5 to 1:1.4.

Filled bag has a total  weight of  assembly  of  45,5  kg  ±  0,5 kg
Tape bag with 13  mm  wi de  tape  use  3  rol ls  (165m)  and tape  in  diagonal ,  overlapping  manner .  Cover  entire  surface of  bag.  Tape  neck separately.

b) A test frame similar to that shown in Figure 6 and Figure 7 shall be provided to minimise movement and deflection during testing. The structure framing and bracing shall be steel channel (approximately 100 mm x 200 mm or larger) and shall have a minimum moment of inertia of approximately 187 cm 4. 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
