Parts that withstand the glow-wire test of IEC 60695-2-11, but which, during the test, produce
a flame that persists for longer than 2 s, are further tested as follows. Parts above the
connection within the envelope of a vertical cylinder having a diameter of 20 mm and a height
of 50 mm are subjected to the needle-flame test of annex E. However, parts shielded by a
barrier that meets the needle-flame test of annex E are not tested.
The needle-flame test is not carried out on parts of material classified as V-0 or V-1 according
to IEC 60695-11-10, provided that the test sample was no thicker than the relevant part.
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
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。 |
