5.8.1 Dust Tests.粉(fen)塵(chen)測試(shi)

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(mu)的:用來(lai)確定當有風(feng)沙(sha)和路面灰塵(chen)幹擾時,附件能(neng)否(fou)提(ti)供(gong)充分(fen)的保護(hu)使(shi)得(de)DUT繼(ji)續達到(dao)CTS中所(suo)指(zhi)明的運(yun)行要求(qiu)。

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(fang)式(shi)1.2）：測(ce)試(shi)根(gen)據(ju)ISO20653針對水(shui)等物體(ti)的防護(hu)。測試(shi)須使(shi)用(yong)ISO12103-1,A2優良等級，同時，粉塵(chen)需持(chi)續8個小時。

Criteria: Functional Status shall be class A.

標(biao)準(zhun)：功(gong)能(neng)狀(zhuang)態(tai)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(bi)免受(shou)損,破(po)壞功能(neng),或(huo)降(jiang)解(jie)其性能(neng)。DUT在(zai)清(qing)潔(jie)前須通過功能(neng)/參(can)數(shu)測(ce)試(shi)。

Q5、ASHRAE和ANSI是什(shen)麽意(yi)思？

ASHRAE 是
American Society of Heating Refrigerating and Airconditioning
Engineers 的縮(suo)寫(xie)，意
思是美(mei)國采(cai)暖(nuan), 制冷與(yu)空調工程師(shi)學(xue)會(hui)；
ANSI
是 American National Standards Institute
的縮(suo)寫(xie)，意思是美(mei)國國(guo)家標(biao)準(zhun)協(xie)會(hui)；

Q6、同樣(yang)尺(chi)寸塑(su)料瓶裝的ISO 12103-1 A2 Fine試驗粉塵(chen)的重(zhong)量為何(he)比(bi)ISO 12103-1
A4輕(qing)約(yue)壹公斤(jin)？按理說(shuo)A2粉(fen)塵(chen)含有(you)更多(duo)小顆粒，那(na)應該重(zhong)量更重(zhong)才(cai)對啊(a)？為何(he)實(shi)際(ji)情(qing)況(kuang)正(zheng)好(hao)相(xiang)反(fan)？

ISO
12103-1 A2 Fine Test Dust
的確是含(han)有更多(duo)的小顆粒，同樣(yang)容(rong)積的塑(su)料瓶內A2的試驗粉塵(chen)顆粒數(shu)目(mu)也相(xiang)對(dui)於(yu)ISO 12103-1 A4 Coarse Test
Dust 更多(duo)。

　　但(dan)是，較(jiao)大尺(chi)寸的粉塵(chen)顆粒本(ben)身(shen)的重(zhong)量較之小顆粒要更重(zhong)，雖(sui)然(ran)A4粉(fen)塵(chen)的數量不及A2多(duo)，但(dan)重(zhong)量卻(que)更重(zhong)；另(ling)外，每個單獨的粉塵(chen)顆粒之(zhi)間會(hui)有(you)空氣(qi)存(cun)在(zai)，因(yin)此越多(duo)顆粒，也(ye)就意(yi)味著(zhe)越多(duo)的空氣(qi)，這樣(yang)的後果(guo)就是較(jiao)低的容(rong)重(zhong)。比(bi)如壹加侖(lun)罐(guan)子(zi)裝0-3微(wei)米亞利桑(sang)那(na)道(dao)路試(shi)驗粉塵(chen)，其重(zhong)量大概只有1.5公斤(jin)，而同樣(yang)罐(guan)子(zi)裝ISO粗灰，則重(zhong)達(da)4.5公斤(jin)。
