Please give me a hand !!!

我在關(guān)于電池的UL中發(fā)現(xiàn)有這樣一個(gè)測(cè)試﹕
Mold stress relief test.
Each of thress samples are to be placed in a full-draft circulating-air oven maintained at a uniform temperature of 70.c.

這是個(gè)什么測(cè)試啊? full-draft 又是什么意思呢?

全部回復(fù)(4)

鑄造(材料)去應(yīng)力試驗(yàn)
3只樣品放入空氣充分循環(huán)的70C恒溫烘箱中

以我的了解,電池不用做這個(gè)測(cè)試吧,這個(gè)測(cè)試一般針對(duì)比如帶接線的電池的接線的牢固性啊.

Hi, it's so called "oven test" for plastic enclosure. Acc. to standard IEC60950-1, product with plastic enclosure material shall put in an oven for 70 degree C for 7 hours basically and then evaluate if the enclosure shape is damagned or not for safety concern.
