前辈,谢谢你的信息!; C* d$ k, ?' O# b: T# u% z0 ^
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:
, y! a& l) c0 U3 J* @4 n- p% c# e# `/ N N
条款13.3.1:4 }3 S- ]; W: w" j2 h4 l
13.3.1 Parts of insulating material retaining current-carrying parts in position shall withstand the following tests. 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.
7 }. s5 t2 F* O( G D1 J2 `* Y* z* {& g$ `7 c" I* V
The duration of burning shall not exceed 30 s after removal of the test flame, and any burning drop from the sample shall not ignite the underlying parts as required by IEC 60695-11-5.
$ h0 S" B$ N/ I% j7 Q9 P' ?
( E; Q( I' @$ H1 ?7 R* R" C: KThe requirements of this subclause do not apply in those cases where the luminaire provides an effective barrier to burning drops.
2 X" d+ j7 @) B" _/ o/ A" x0 [8 C) }' f/ M
决议内容:& N0 \, z9 \$ `# A$ k0 f
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?

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。。
