DSH 765（IEC 60065）什么設(shè)備需要做振動試驗(yàn)？

Subject: Vibration Test

Question:

Clause 12.1.2 states “TRANSPORTABLE APPARATUS intended to be used for audio amplification of musical instruments, PORTABLE APPARATUS and apparatus having a metal enclosure, are subjected to a vibration endurance conditioning by sweeping, as specified in IEC 60068-2-6.”

To what kind of equipment is clause 12.1.2 applicable?

a) Is it applicable to equipment with metal enclosure, even if it is not portable or transportable such as a Class I or Class II satellite receiver with metal enclosure?

b) What about “TRANSPORTABLE APPARATUS” intended to be used for audio amplification of musical instruments with a plastic enclosure?

c) What about “PORTABLE APPARATUS” with a plastic enclosure?

d) What about rack mounted audio equipment with a metal enclosure for ELA equipment?

Decision:

The answer to all the above questions is “YES.” The test has to be conducted in every case.

問題：

第12.1.2條規(guī)定“對預(yù)定要作為樂器的音頻放大器使用的可運(yùn)輸式設(shè)備、便攜式設(shè)備以及有金屬外殼的設(shè)備，應(yīng)按照IEC 60068-2-6的規(guī)定，承受掃頻振動耐久性處理?！?/p>

第12.1.2條適用于哪些設(shè)備？

a）是否適用于帶有金屬外殼的設(shè)備，即使不是便攜式或不是可運(yùn)輸式，例如帶有金屬外殼的I類或II類衛(wèi)星接收機(jī)？

b）打算作為樂器的音頻放大器使用的塑料外殼“便攜式設(shè)備”？

c）帶有塑料外殼的“便攜式設(shè)備”？

d）ELA設(shè)備中的帶金屬外殼機(jī)架式安裝的音頻設(shè)備？

決定：

以上所有問題的答案都是“是”。每種情況下都必須進(jìn)行測試。

提示：

以下是2000年2月21日至25日在惠靈頓舉行的TC92/WG1會議紀(jì)要的摘錄

第12.1.2條第1段：應(yīng)對所有帶有金屬外殼的設(shè)備進(jìn)行振動測試，無一例外。

這帶來了以下問題。

1）金屬封閉的、永久連接的設(shè)備是否經(jīng)受此測試？是

2）重 (>100kg) 設(shè)備是否需要進(jìn)行此測試？是

3）如果只有后蓋是金屬的，設(shè)備是否要進(jìn)行這項(xiàng)測試？不

4）在聚合物外殼的外部只有一個“小”金屬檢修面板的設(shè)備是否需要進(jìn)行此測試？不

5） 如果安全不依賴于可觸及外殼，例如自動點(diǎn)唱機(jī)，而依賴內(nèi)部金屬殼來防止電擊危險，該設(shè)備是否經(jīng)受此測試？是

點(diǎn)擊下方名片，關(guān)注“朱大俠的質(zhì)檢江湖”微信公眾號，一起來研究安規(guī)吧~
