刚看了一下,电热器具的第2部分基本上都有说明限制热散发的方法,caballo3157的说法应该是正确的。8 P+ I! ?$ G0 ]
不过我在做卷发棒的时候,发现19.2里面有说明一些产品的限制热散发方法,但是没提到卷发棒。请问这时候应该怎么做19.2?1 N9 _1 [* B9 Y1 M5 U

Restricted heat dissipation is obtained as follows:

– hand-held hairdryers are placed on the floor of the test corner in any stable position likely to occur;/ Z3 a7 i* B$ v
– appliances intended to be filled with water are operated empty.4 B. l0 T4 w3 q9 Y3 @1 t
Hairdryers having a flexible hood attachment are also tested with the motor operating, the airflow through the hose being restricted to give the most unfavourable result.2 Z$ l% A, t$ A, K
Heaters 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. (我做的产品不属于detachable curlers) |
