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./ j, q! R, a: I9 Z, I8 C, h( U
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) |
