Significance and Use
This test method is for use in evaluating the capability of a container or shipping system to withstand sudden shocks and crushing forces, such as those generated from rail switching impacts or pallet marshalling, or to evaluate the capability of a container and its inner packing, or shipping system, to protect its contents during the sudden shocks and crushing forces resulting from rail switching or pallet marshalling impacts. This test method may also be used to compare the performance of different container designs or shipping systems. The test may also permit observation of the progressive failure of a container or shipping system and damage to the contents. See Practice D 4169
This test method is not suitable for reproducing impact resulting from the switching of rail cars using long-travel draft gear or cushioned underframes. Refer to Method D 4003
1.1 This test method covers the procedures for reproducing and comparing shock damage, such as that which may result from rail switching or pallet marshalling impacts, using an incline impact tester. It is suitable for simulating the types of shock pulses experienced by lading in rail switching of rail cars with standard draft gear, but not for those with long travel draft gear or cushioned underframes. The test method can also be used for pallet marshalling tests.
