8.4.3 According to the circumstances of use, handlamps shall be classified as rough service luminaires。

8.10.2 中有Flexible cable and cords shall be polychloroprene sheathed.0 Y$ x- n! o; l' a$ \
其中H05RN-F和H07RN-F都属于氯丁护套软线,这个解释在EN 60335-1家电标准中有解释。$ L" \2 B! l1 V* V0 h. T# W6 v
再看EN 60598-1通标中,恶劣条件使用下的灯具,电线应至少为H07RN-F。
