DSH 540/542/547（IEC 60950-1）筆記本電腦底部是可觸及部件/繞組線的螺旋纏繞層要求/交互終端標(biāo)準(zhǔn)

DSH 540

Subject: Parts likely to be held or touched during normal use on a portable (laptop) computer

Question:

On a portable (laptop) computer; are parts of the equipment underside considered to be parts likely to be held or touched during normal use such as would be subject to test condition a) of subclause 6.2.1?

Decision:

Given the likely use of a portable (laptop) computer; the underside of the equipment enclosure is a part likely to be held or touched during normal use and is tested as per test condition a).

問題：

便攜式（筆記本）電腦的底部是否被認(rèn)為是在正常使用中可能被抓握或接觸的部件，應(yīng)符合第6.2.1條款（a）要求 ?

決定：

考慮到可能使用便攜式（膝上型）電腦，設(shè)備外殼底部是正常使用中可能被抓握或接觸的部件，按照條件a進(jìn)行測試。

提示：

1、規(guī)定只適用于與通訊網(wǎng)絡(luò)連接的便攜式（膝上型）電腦；

2、正常使用中可能被抓握或接觸的部件相比于只能用手指接觸的部件，其抗電強(qiáng)度要求更高。

Subject: Application of Annex U and 2.10.8 to spirally wound insulation required to be treated as a cemented joint

Question:

When applying the 3rd paragraph of 2.10.5.4, what is the intent of the requirement for spirally wrapped insulation (tape) when the CLEARANCES and CREEPAGE DISTANCES between layers, as wrapped, are less than the required minimum value for Pollution Degree 1?

Decision:

The intent is, if the CLEARANCES or the CREEPAGE DISTANCES between layers, as wrapped, are less than the required minimum value for Pollution Degree 1, the spirally wrapped insulation should be sealed and pass the tests of both:

· Annex U, which requires an electric strength test per Annex U.2 at the voltage specified in U.2; and

· 2.10.8, which requires an electric strength test of 1.6 times the values in 5.2.2 after the testing in 2.10.8.

問題：

當(dāng)繞組螺旋纏繞膠帶層間的電氣間隙和爬電距離小于污染等級1要求時(shí)，標(biāo)準(zhǔn)規(guī)定的意圖是什么？

決定：

如果繞組纏繞膠帶層間的電氣間隙和爬電距離小于污染等級1要求，則螺旋纏繞層應(yīng)當(dāng)密封并通過如下2個(gè)試驗(yàn)：

1、附錄U的抗電強(qiáng)度試驗(yàn)；和

2、濕熱處理后的抗電強(qiáng)度試驗(yàn)（試驗(yàn)電壓為5.2.2條款的1.6倍）

提示：

1、決議對應(yīng)IEC 60950-1第1版，新版本標(biāo)準(zhǔn)條款號與決議中提示有差異，但核心內(nèi)容基本一致，故而翻譯稿中不提及條款號；

2、由粘合劑密封的繞組線上的螺旋纏繞層間可以認(rèn)為是粘合的接縫。

Subject: Standard for interactive terminals

Question:

Which standard shall be applied for type testing equipment as described below：

Decision:

IEC 60950 is applicable as long as the product is not configured by the OEM’s customer (reseller) and submitted specifically for an application covered under the scope of IEC 60335-2-75 (e.g., audio/video disc vending).

問題：

下述設(shè)備的型式檢驗(yàn)應(yīng)采用哪個(gè)標(biāo)準(zhǔn)？

產(chǎn)品描述：用于支付系統(tǒng)的工業(yè)和個(gè)人交互式終端。它能夠管理處理數(shù)據(jù)的外圍設(shè)備（讀卡器、打印機(jī)、硬幣比較器和銀行鈔票驗(yàn)證器）。交互式終端通過以太網(wǎng)連接作為“主”計(jì)算機(jī)的“從機(jī)”工作。交互式終端的最終應(yīng)用在很大程度上取決于安裝在“主”計(jì)算機(jī)上的軟件。因此，交互式終端的最終用途取決于“主”計(jì)算機(jī)安裝/網(wǎng)絡(luò)的所有者的意圖。

決定：

IEC 60950是適用的，只要產(chǎn)品不是由OEM的客戶（經(jīng)銷商）配置的，并特別提交了適用于IEC 60335-2-75范圍內(nèi)的申請(例如，音頻/視頻光盤出售)。
