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。3 m8 |! T% ?, N8 O
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?# `' D- r+ H1 i+ l S+ h
19.2 Addition:

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. |# T# n+ a$ W. F* `9 y
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) |
