         各位前辈，我想请教一个问题，就是吹风机19.2的测试条件：

1 e2 O( R, Z" I' y" `5 z( p7 G19.2 Addition:
- i- |7 Y2 x% G/ ]& @Restricted heat dissipation is obtained as follows:
– motors are disconnected;
– hand-held hairdryers are placed on the floor of the test corner in any stable position
9 g& p& s' X5 t# klikely to occur;
5 u6 l0 B' a( m2 w" x! D– appliances intended to be filled with water are operated empty;
$ v9 g% O/ U3 g  |* t– hand-held appliances without an integral rest are placed on the floor of the test corner in
any stable position likely to occur.
2 V4 F0 X: l0 u8 `' \Hairdryers having a flexible hood attachment are also tested with the motor operating, the
( o5 {0 j2 o! q( Q) |7 M* Dairflow through the hose being restricted to give the most unfavourable result.
1 P- r7 l9 B8 R9 O4 A& a& ^/ LHeaters for detachable curlers are placed on a piece of low-density glass-fibre insulation
having a coefficient of thermal insulation of approximately 2,5 m2K/W.

8 R$ H  A- F" h& Y   这些条件是独立的做多个实验 还是同时满足做一个实验？

请大家指点，谢谢。

每个单独试验吧，都应符合吧，我这么理解的

是一个测试，如果分开模式测试的话标准会进行说明，例如IEC 60335-2-25的19.103：
19.103 Appliances are operated under normal operation and with any single fault condition
simulated that is likely to occur. The controls are adjusted to their most unfavourable setting

is shorter.
NOTE Examples of fault conditions are

然而CB机构都是单一故障去做每个符合的条件，比如电吹风就是断开电机测一次，放在平放在测试角测一次

这个TC61有解释过，应该是分开情况测的
