Question:1 Y9 p- V$ { `$ n" K, Z' u9 V' n
During the test of protection against electric shock for luminaires, in some cases a live metal part A1 {- ]5 J" o6 E, p. P6 @* v. V
projected from lamp cap E 27 can be accessible with the standard test finger. When the compliance of the
% z% b6 A0 l6 Sused lamp and the built-in lampholder were checked with the relevant requirements of IEC 60432-1" x7 a( m$ d3 N
and IEC 60238, they were found as satisfied. But the live part accessibility within the luminaire was
1 L$ D. M& W1 wcaused by such a metal part projected from the lamp cap which is acceptable according to the sub clause5 j3 s& h5 l) I, C# x
2.7.3 of IEC 60432-1. “On Edison screw caps any projection from the cap shell shall not project more& o( K$ X* S0 V+ A
than 3 mm from the surface of the cap. See figure 1”. In this case there can easily come into existence a
