我的理解是只要是产品外壳内部所有的塑胶零部件都需要做850度的灼热丝测试,而且一点火都不能起,也就是不是按照通常的判定方法:点火30秒,移开后30秒要熄灭来判定。
$ o I- _. k' ?1 \6 W# @问题点是:哪些部件需要测试灼热丝,标准表达得非常模糊。以上in the enclosure, in fan blades and in all structural elements with the enclosure都用到了3个in, 是指外壳里,风扇叶片里,和外壳内部的结构性元件吗?/ X* [9 w4 _+ Q, [: U3 Y+ p2 t8 H

上面讲到的substantially non-metallic material 是什么意思?
