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。5 }* m2 ^$ s8 s$ ?. M
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?

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.
