試驗粉塵


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 complete blockage 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ISO20653針對水等物體的防護。測試須使用ISO12103-1,A2優良等級,同時,粉塵需持續8個小時。
Criteria: Functional Status shall be class A.
標準:功能狀態須為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 test prior to cleaning.
DUT應避免受損,破壞功能,或降解其性能。DUT在清潔前須通過功能/參數測試。
