标题: Bare unit drop test (International) - Retail
This document establishes a Product Reliability Test Plan for the Audio Business Unit.
This testing validates the product design against bare body drop occurrences.
2.
Scope:
This plan applies to all Audio products.
The plan specifically notes:

3.
Reference Documents:
[1] Product Qualification Test Methods, NPP Notes database
4.
Qualification Test(s):
This test is essentially a sequence of five to seven drops of the bare product to validate that the product will continue to function after reasonable abuse.
The height of the drops depends on the use scenario for the product / component.
4.1.
Bare Unit Drop:

4.1.2.
Test Method:
1.
Verify proper device operation prior to drop test.
2.
Determine the drop height as per the product use model (see table below).
3.
Configure the fixture / drop machine for this height.
4.
Drop the device 5-7 times, once per face as per the orientation / sequence table excluding any permanent cable / corded side (5 drops).
5.
After each drop, inspect the product for damage as per the acceptance criteria.
6.
After all drops are completed test the product for functionality.
For satellites and subwoofers, disassemble and inspect driver baskets for bending and screw pull out.

Satellites and all other:
-
all 6 faces except the side with cord if cord is permanently attached
-
Standard drop orientation sequence (6 drops).

Drop orientation sequence with permanently affixed cable/wires (5 drops).

4.1.3.
Test Criteria:
Drop Height:
Test height as outlined in table below,
# of Drops:
5-7 (once per orientation)
Temperature:
ambient (20°C to 35°C)
Humidity:
30 % to 80 %
Sample quantity:
5 units
Critical parameters:
product functionality structural and cosmetic inspection with each drop, functional evaluation at completion of all drops

Check interval:

Classification Table for Drop Test Heights

Category	Drop Height
Headsets	2 meters	ç previous ABU standard
Headphones	2 meters	ç previous ABU standard
Handheld microphones	2 meters
Speaker satellite	100 cm	ç previous ABU standard
Speaker control pods	100 cm
Power adapters	100 cm
USB dongles	100 cm
Wireless dongles	100 cm
Desktop microphones	100 cm
Subwoofer	30 cm

4.1.4.
Acceptance Criteria:
·
Product must be fully functional.
No operational degradation is allowed.
·
Cosmetic damage is acceptable if it does not deter from the product functionality.
·
Stands must still hold the product upright (though cracking is allowed).
·
All electronics must remain in-accessible to the user.
Housings must not crack open.
·
User recoverable failures are acceptable.
These include battery doors popping open, satellite stands popping off… as long as these are easily reassembled by the consumer and that they do not constitute a safety hazard to the consumer.
·
No air leakage should result in the satellite or subwoofer.
·
All drivers (satellite and subwoofers) must remain affixed in place.
No screws can pull free and the driver basket cannot deform (disassembly may be required for inspection of the driver baskets)
