Parts that withstand the glow-wire test of IEC 60695-2-11, but which, during the test, produce

以上是我从30.2.3.2 of IEC60335里复制下来的内容。"but which, during the test, produce - N7 Y0 M* Z8 O4 D2 P
a flame that persists for longer than 2 s, are further tested as follows."很明显,是在测试过程中的持续燃烧两秒,而不是样品离开灼热丝后燃烧两秒。 |
