以前做过带电池和TNV电路的网关,挤压冲击和跌落都做了。是因为三个测试判定的地方不一样。挤压不用说了,跌落是看外壳受到跌落的应力内部电池有没有问题,冲击是看外壳受到冲击后会不会碰触到TNV电路。不同情况不同测试。1 T( | e7 x! H# M

所以个人认为还是按照功能来。根据不同的工作模式,符合跌落的工作模式就做跌落,不符合跌落的工作模式就做冲击。都有那么都做。作者: jcyxb 时间: 2015-11-25 11:40 本帖最后由 jcyxb 于 2015-11-25 11:41 编辑 4 f7 S9 a2 U1 T2 P1 F/ k9 a# c( `/ i# i5 V+ t

60950 做冲击不做drop,60065中没有这样说。
