DSH 624A（GENERALITY）濕熱處理的環(huán)境條件能否統(tǒng)一？

Subject: Humidity test requirements

Question:

Various IEC standards have requirements for humidity / temperature conditioning, but have different specifications for the test conditions.

- IEC 60065 – 93% +/- 3% (t 20-30℃ +/- 2℃ or 40℃ +/- 2℃);

- IEC 60950-1 – 93% +/- 3% (t 20-30℃ +/- 2℃ or 40℃ +/- 2℃);

- IEC 60601-1 – 93% +/- 3% (t 20-30℃ +/- 1℃);

- IEC 61010-1 – 93% +/- 3% (t 40℃ +/- 2℃);

- IEC 60335-1 – 93% +/- 3% (t 20-30℃ +/- 1℃).

There does not seem to be a technical justification for the differencies in the specifications. Accordingly, it is suggested and recommended that the humidity / temperature specifications in the above standards be consistent.

Decision:

The chamber is to be set at 93% RH, with +/- 3% RH tolerance, at a convenient temperature between 20℃ and 30℃ or an appropriate higher temperature when required by the specific product standard, but the chosen temperature to be kept within +/- 2℃ during the test.

The standard specifications for the humidity are to be met at the reference / measuring point, where the controlling humidity sensor is located.

問(wèn)題：

各IEC標(biāo)準(zhǔn)都對(duì)濕度/溫度調(diào)節(jié)有要求，但對(duì)測(cè)試條件有不同的規(guī)范。

- IEC 60065    – 93% +/- 3% (t 20-30℃ +/- 2℃ or 40℃ +/- 2℃);

- IEC 60950-1 – 93% +/- 3% (t 20-30℃ +/- 2℃ or 40℃ +/- 2℃);

- IEC 60601-1 – 93% +/- 3% (t 20-30℃ +/- 1℃);

- IEC 61010-1 – 93% +/- 3% (t 40℃ +/- 2℃);

- IEC 60335-1 – 93% +/- 3% (t 20-30℃ +/- 1℃)。

標(biāo)準(zhǔn)差異似乎沒(méi)有技術(shù)理由。

因此，建議和推薦上述標(biāo)準(zhǔn)中的濕度/溫度條件保持統(tǒng)一。

決定：

環(huán)境設(shè)置在93%RH，具有+/-3%RH容差，在20℃至30℃之間的合適溫度或特定產(chǎn)品標(biāo)準(zhǔn)要求的更高溫度，但在測(cè)試過(guò)程中要保持在所選溫度的±2℃以?xún)?nèi)。

在控制濕度傳感器所在的參考/測(cè)量點(diǎn)達(dá)到濕度的標(biāo)準(zhǔn)條件。

提示：

決議大意是兩個(gè)：

1、沒(méi)聲明更高要求時(shí)，按對(duì)應(yīng)標(biāo)準(zhǔn)條件作為默認(rèn)條件；

2、濕度測(cè)量點(diǎn)以傳感器所在位置為準(zhǔn)。
