UL60065防火外壳

是不是零件要符合20.1的要求并且外壳要符合20.2

有了防火外壳一般的零件对引燃源还有具体要求么

UL60065防火部分到底要怎么看

里面沒有危險電壓，外殼開孔就沒有任何要求嗎？對里面的零件有什麽要求呢？如果rating是12V/1.5A.....


有沒有高人指點啊！！！！

20.1.1 Electrical components
Electrical components shall comply with the relevant flammability requirement of clause 14.
Where there are no applicable flammability requirements in clause 14, the requirements
of 20.1.4 apply.
Compliance is checked by appropriate tests of clause 14 or 20.1.4

对零部件的要求，请看回20.1。1章节。

20.1.3 PRINTED BOARDS
Base material of PRINTED BOARDS, on which the AVAILABLE POWER at a connection exceeds
15 W operating at a voltage exceeding 50 V up to and including 400 V (peak) a.c. or d.c. under
normal operating conditions, shall be of flammability category V-1 or better according to
IEC 60695-11-10, unless the PRINTED BOARDS are protected by an enclosure meeting the
flammability category V-0 according to IEC 60695-11-10, or be made of metal, having openings
only for connecting wires which fill the openings completely.
Base material of PRINTED BOARDS, on which the AVAILABLE POWER at a connection exceeds 15 W
operating at a voltage exceeding 400 V (peak) a.c. or d.c. under normal operating conditions, and
base material of PRINTED BOARDS supporting spark gaps which provide protection against
overvoltages, shall be of flammability category V-0 according to IEC 60695-11-10, unless the
PRINTED BOARDS are contained in a metal enclosure, having openings only for connecting wires
which fill the openings completely.
Compliance is checked for the smallest thickness of PRINTED BOARD used, in accordance with
either:
a) IEC 60695-11-10; or
b) with Clause G.1 on specimens of boards as used in the apparatus, but without components.
The tests under b) are performed after a preconditioning of 24 h at a temperature of
(125 ± 2) oC in an air-circulating oven and a subsequent cooling period of 4 h at room
temperature in a desiccator over anhydrous calcium chloride.
