D03021940G-00 Datasheet, PDF (8/14 Pages) List of Unclassifed Manufacturers – SPECIFICATION FOR APPROVAL

III. OTHER SPECIFIED TESTING
The following is a general description of certain tests that are performed on representative
Sunon fans. Nothing in this document is intended to suggest that these tests are performed
on every model of Sunon fan. Moreover, the descriptions that follow each test are meant
only to provide a general explanation of each test. If you would like a more detailed
explanation as to any test identified in this Section, Sunon can provide such an
explanation upon request.
1. DROP PROOF TEST
Fans are packaged in a standard size shipping box and are dropped to the ground from
certain heights and angles depending on the weight of the particular box.
2. HUMIDITY PROOF TEST
The fan is operated for 96 continuous hours in an environment with humidity of 90% to
95% RH at 60°C ± 2°C.
3. VIBRATION PROOF TEST
Vibration with an amplitude 2mm and a frequency of 5-55-5hz is applied in all 3
directions (X,Y,Z), in cycles of 1 hour each, for a total vibration time of 3hours.
4. THERMAL CYCLING TEST
The fan is operated in a testing chamber for 50 cycles. In each cycle, the temperature is
gradually increased from -10°C to 70°C for 90 minutes, and subsequently operated at
70°C for 120 minutes. The temperature is then gradually decreased from 70°C to -10°C
for 90 minutes, and subsequently operated at -10°C for 120 minutes.
5. SHOCK PROOF TEST
100G of force is applied in the 3 directions (X,Y, and Z) for 2 milliseconds each.
6. LIFE EXPECTANCY
The “Life Expectancy” of SUNON fans is determined in SUNON’s reliability test
laboratory by using temperature chambers. The “Life Expectancy” of this fan has not been
evaluated for use in combination with any end application. Therefore, the Life Expectancy
Test Reports (L10 and MTTF Report) that relate to this fan are only for reference.
