4 {4 ?0 }" Q. W5 y2 Q2 V7 w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。
* P6 g ^' v% x' A! a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?
2 V z) o# z: Q什么是外壳内部结构性元件?
