前辈,谢谢你的信息!
u/ z3 A2 p) R6 r! j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:$ V4 M& t# M& a7 i
1 o6 z9 C4 k! B
条款13.3.1:
0 E) t9 p; @1 A# U2 n3 u: _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. 6 X i% S8 J9 F% z
4 d* Z. d8 g" S8 D3 g1 A3 t0 p, k
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. 2 L. N7 p% I* w- b! q
% c+ F. w1 A, | [. C6 ^. w
The requirements of this subclause do not apply in those cases where the luminaire provides an effective barrier to burning drops. ( \ y; D) ^6 ^8 _
1 A3 G- C% E( L
决议内容:' p4 K) V5 O) @- _$ y7 l
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? 2 s' |: R$ v# i0 k# ^

Decision:, E, N+ ?+ I* m
Needle-flame test and glow-wire test (650°) are required.

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。。
