2、rmament, Munitions and Chemical Command, and is available for use by all Department and Agencies of the Department of Defense. 3.10.1 Accelerated storage aging verification. Add the following paragraph: 3.10.1 Accelerated storage aging verification. All HED Battery (Dwg. 93281871 samples for First A
3、rticle Testing shall be conditioned for 21 days at 215OF + 5OF prior to testing for the requirements of 3.3, 3.4, 3.5, 3.11, 3.12 and 3.13. During production, a continuous sample of 5 batteries per hour shall be taken from each lot and subjected to 215OF + 5OF for 21 days. If after conditioning, the
4、 batteries meet the non-activation voltage requirements of 3.3, lot acceptance samples will be taken from the production lot and subjected to lot acceptance testing. If after conditioning the batteries do not meet the non-activation voltage requirement of 3.3, then the entire lot shall be rejected.“
