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。
( ?2 a u/ ?$ ^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 R. y2 q; f9 I$ j- V6 h7 L

Restricted heat dissipation is obtained as follows:: w! B6 L8 {& f& o' Z6 d

– appliances intended to be filled with water are operated empty.5 r d8 e; @, j8 b9 y8 {
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.. o9 g3 D* d- Z) H3 `
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) |
