5.8.1 Dust Tests.粉尘测试

Purpose: To determine if the enclosure provides sufficient protection from dust intrusion from

windblown sand and road dust to allow the DUTto continue to meet the performance requirements

specified in the CTS. The accumulation of dust on heat sink devices will adversely affect heat dissipation. Dust may also combine with humidity and salt to produce unintentional conductive paths. Dust accumulation will adversely affect electro-mechanical devices resulting in increased friction or completeblockage of motion.

目的:用来确定当有风沙和路面灰尘干扰时,附件能否提供充分的保护使得DUT继续达到CTS中所指明的运行要求。

Procedure （Operating Type 1.2）: Test according to ISO 20653 Protection against objects, water

and access. This test shall be conducted using ISO 12103-1, A2 Fine Grade Dust and should occur

for a period of 8 hours.

过程（操作方式1.2）：测试根据ISO20653针对水等物体的防护。测试须使用ISO12103-1,A2优良等级，同时，粉尘需持续8个小时。

Criteria: Functional Status shall be class A.

标准：功能状态须为A级

The DUT shall experience no damage, loss of function, or degradation of performance. The DUT shall pass the Functional/Parametric Test at the end of testprior to cleaning.

DUT应避免受损,破坏功能,或降解其性能。DUT在清洁前须通过功能/参数测试。
