5.8.1 Dust Tests.粉塵測試

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:用來確定當有風沙和路面灰塵干擾時,附件能否提供充分的保護使得DUT繼續(xù)達到CTS中所指明的運行要求。

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.

過程（操作方式1.2）：測試根據(jù)ISO20653針對水等物體的防護。測試須使用ISO12103-1,A2優(yōu)良等級，同時，粉塵需持續(xù)8個小時。

Criteria: Functional Status shall be class A.

標準：功能狀態(tài)須為A級

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應(yīng)避免受損,破壞功能,或降解其性能。DUT在清潔前須通過功能/參數(shù)測試。
