Product Qualification testingKey product Qualification tests performed for acceptance• Functional verification (display, scanner, battery, Keyboard, WLAN radio, scanner interface) • Thermal Shock (MIL-STD 810 F method 503 standard profile -40 - +70 C rapid transition)• Vibration (MIL-STD 810 F method 514 procedure I, 1 hr per axis, 3 axis)• Operational Temperature Cycling (MIL-STD 810 F method 520.2 industrial, -20C to +50C)• ESD (EN61000-4-2) 8KV/15kV• LOW temp storage (MIL STD 810F Methods 502.4)• HIGH temp storage (MIL STD 810F Methods 501.4)• Cargo packaged drop (ASTM D775-80 & MIL STD 810F Method 514,Procedure II)• Cargo unpackaged drop (ASTM D775-80 & MIL STD 810F Method 514,Procedure II)• Drop shock testing (MIL STD 810F= Method 516.5, Procedure IV, 36 drop @ 48” )• Tumble (EN60069-2-31 formerly IEC 68-2-32, 1 meter or ½ meter)• Electrical EMC compliance (EN61000-4-3, 4-4, 4-5, 4-6, 4-8, 4-11)• EN60529 Dust seal IP6X• EN60529 Water ingress IPX7• Battery drops testing over operating temperature

IPX7 per EN60529
Water exposure to verify seal integrity of the enclosure
Immersion, 1 meter water, 30 minutes
1 meter immersion tank (product test) Vacuum testing (product & component test)
Vacuum testing performed on:
• Monocoque enclosure
• End cap assembly
• Keypad assembly
• Final assembly MC95XX

1 meter tumble 2000 cycles (4000 impacts)
Tumble Per EN60068-2-31
Verify mechanical durability and assembly integrity
1 Meter tumble, 2000 cycles (4000 drops)

• 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

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
