projected from lamp cap E 27 can be accessible with the standard test finger. When the compliance of the" O t" U+ c3 ]2 j% w
used lamp and the built-in lampholder were checked with the relevant requirements of IEC 60432-1

caused by such a metal part projected from the lamp cap which is acceptable according to the sub clause
