• Drop testing can is done per Motorola method & MIL-STD-810F method 516.5

• What is important to know….– Each product may or may not meet certain aspects of the Mil-Std-810F test

method…The MIL-STD methods does not specify pass fail criteria….

– Drop Considerations…3 samples dropped in each case.

Moto MC95 MIL-STD-810F tm 516.5

Is the unit on? Unit operating Unit not operating, loss of data is allowed

Is the surface concrete? Concrete* 2” Plywood over concrete

Over temperature range? Cold, room, hot 25C only

Number of drops? 36 drops/sample 26 drops total for all samples

Corners ,edge & surface

• Advantage • Motorola performs drop testing to not one but BOTH methods shown

above

Deep Dive on drop testing
