从决议本身,并不能看到说接受外壳具有足够防火等级,内部器件可不做针焰;问题本身标准都没有出处,而后面 ... 3 Z% l' d' E3 n. U/ c
前辈,谢谢你的信息!& ^8 [1 A z5 T) @
前几日,论坛网友提供了一项决议,DSH 0930,由于软件限值,无法提供截图,我把内容写一下,它是和60598的13.3.1条款相关的:9 D% {+ V. {; ~# `2 n

The parts to be tested are subjected to the needle-flame test of IEC 60695-11-5, the test flame being applied to the sample for 10 s at the point where the highest temperatures are likely to occur, measured if necessary during the thermal tests of Section 12.

Question: If an effective barrier to burning drops is provided, the needle-flame test is not applied on parts of insulating material which retain current-carrying parts in position (e.g. terminals). Could a plastic enclosure of luminaire providing a barrier to burning drops and having passed the glow-wire test at 650°, be regarded as an "effective barrier" or should such part withstand the needle-flame test? * U$ A- U' e. y8 L/ f0 [! g7 j1 |

上面这句是说外壳可以当barrier,还是说端子必须满足针焰和灼热丝650呢?之前我理解是允许外壳当做barrier的,今天看看大家的回复,有些不淡定了。。: F+ i, {2 p! m$ M% z( Q8 |# C7 Z' a. u
