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:
$ m* _$ @* X! f3 Y5 @3 Q8 |0 j, ?9 N7 B8 k- S1 X1 a
条款13.3.1:
7 I% z; |7 ~7 q5 V6 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. , }- F& [9 h' d% p
) i) b. u- S$ F( l
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.
. q$ L1 W/ d' @5 A8 v& O) W/ @3 ^ W# U$ @! H$ [( J' M, U: Q: U
The requirements of this subclause do not apply in those cases where the luminaire provides an effective barrier to burning drops. ~$ O' g5 Y6 ~: e3 s+ Q# ^1 M
+ r% ^$ F( L8 t% s
决议内容:
2 j& t6 C* T# m+ W& O( BQuestion: 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? 9 `0 F: k( W* _8 |4 ?2 e- S

Decision:0 x! G4 D: g% z. b3 u3 R9 m
Needle-flame test and glow-wire test (650°) are required. ! Q" a7 x% `3 A

3 }* `; ]+ r* s( h 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。。
