ylgc123,谢谢解答,但是我还是没明白你的意思。。。。
5 F! `3 F' W- }2 I0 K& O60335-1里面提到的灼热丝试验,是直接引用60695-2-11,而在60695-2-11里面,是明确指出小部件不做灼热丝的。附件1是我从60695-2-11的截图。

所以,我理解是,60335灼热丝的前提是,小部件不做。7 ^# n) T1 f+ w( X$ H$ ^
而且30.2.3.1 的850℃说的是:parts of non-metallic material supporting connections that carry a current exceeding 0.2A during normal operation,and parts of non-metallic material ,other than small parts, within s distance of 3mm of such connections, are subjected to the glow-wire test of IEC 60695-2-11 with a test severity of 850℃。( t8 P0 l( n5 A4 X
已经把small parts给other than排除掉了。, V5 A( E1 J9 @$ T$ ?& }
