第一疑问:
- P6 t3 d1 W& q6 u, b8.4.3 According to the circumstances of use, handlamps shall be classified as rough service luminaires。
, X7 D7 s3 k4 E# e此时即为IP54防护的灯具,怎么还会有0,75 mm² for ordinary handlamps的说法?3 ~4 Z# Z. I- ^: E2 F( O3 W

. K. U5 y4 L, r4 }1 K 8.10.2 中有Flexible cable and cords shall be polychloroprene sheathed.
( Q1 Q7 }4 w" m/ L5 [' p 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。
