小弟有個(gè)IEC60335-1的問(wèn)題,還請(qǐng)各位大哥指教.
****30.2.3.1 Parts of insulating material supporting connections that carry a current exceeding
0,2 A during normal operation, and parts of insulating material within a distance of 3 mm of
such connections, shall have a glow-wire flammability index of at least 850 °C according to
IEC 60695-2-12, the test sample being no thicker than the relevant part.
***30.2.3.2 Parts of insulating material supporting current-carrying connections, and parts of
insulating material within a distance of 3 mm of such connections, are subjected to the glowwire
test of IEC 60695-2-11. However, the glow-wire test is not carried out on parts of
material classified as having a glow-wire ignition temperature according to IEC 60695-2-13 of
at least
– 775 °C, for connections which carry a current exceeding 0,2 A during normal operation;
– 675 °C, for other connections,
provided that the test sample was no thicker than the relevant part.
When the glow-wire test of IEC 60695-2-11 is carried out, the temperatures are
– 750 °C, for connections which carry a current exceeding 0,2 A during normal operation;
– 650 °C, for other connections.
對(duì)載流超過(guò)0.2A的部件來(lái)說(shuō),30.2.3.1和30.2.3.2的兩個(gè)試驗(yàn)是不是都要做?而這兩個(gè)試驗(yàn)的測(cè)試方法和結(jié)果的判斷有什么不同(也就是國(guó)標(biāo)中所謂的灼熱絲起燃指數(shù)試驗(yàn)和灼熱絲試驗(yàn))?哪位大哥有IEC 60695-2-11和IEC 60695-2-12標(biāo)準(zhǔn)能弄來(lái)看看?
