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 ...

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:+ r" a, q5 l8 L+ I$ `* D
% V @4 u. v' R* o( Z4 B条款13.3.1:
0 J V% i2 ~& a. L13.3.1 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.
" z3 ]* O) ~# Z6 D: n- h5 J0 f( k- b$ N8 k" j, A
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.
, _8 Y8 t. [7 Z; w. m$ }, W* o# |% V
The requirements of this subclause do not apply in those cases where the luminaire provides an effective barrier to burning drops.

& x( c4 a1 h: E( C5 ~/ \' VQuestion: 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?

Needle-flame test and glow-wire test (650°) are required. 2 I6 r0 Y. Q7 X% `8 O6 }! {7 a! ^

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。。 r# \) m4 d5 ^0 `
