Drop testing can is done per Motorola method & MIL-STD-810F method 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 MC95MIL-STD-810F tm 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

9:36:55 AM 8 Drop Slide Test performed in proprietary AFM testing Accelerated Failure Mode (AFM) is reliability testing beyond spec. Real life accidentally drop of product, on Concrete Parameters: Height:4' Drop Distance:6' Slide Distance:1-1.5' Orientation # 1:Top Face + Up, Down, Left, Right Orientation # 2:Bottom Face + Up, Down, Left, Right Drops per cycle:8 Temperature:+25°c, +50°c, -20°c Drop testing (Continued) 1-1.5' Drop Slide Test Wall 4' 6'
