ylgc123,谢谢解答,但是我还是没明白你的意思。。。。
7 B3 l+ G6 n: j' E! f, F8 h; H% \4 l60335-1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。" _8 `- {5 z2 w( N4 g! q
1 v: Q! X+ I4 U
所以,我理解是,60335灼热丝的前提是,小部件不做。4 \1 i' y9 g9 X" \. y: m
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℃。
9 j! l7 T# n$ l2 L3 d0 s已经把small parts给other than排除掉了。0 w/ b% P A9 @1 K0 f* M
' {) _" i, F+ V7 C1 k5 U$ D
不知道我的理解是否正确??
