Test Conditions
Subject sample to 2-mimute cycles (frequencies from 10 to 500Hz) with 1.5mm
amplitude or 100g acceleration during 2 hrs in each direction (X,Y,Z). 6 hours in total.
Orient the sample in any attitude and drop it 3 times from a height of 50cm onto a
hardwood board with a thickness of 3cm.
