During the test of protection against electric shock for luminaires, in some cases a live metal part" f0 R0 c& g1 E2 v
projected from lamp cap E 27 can be accessible with the standard test finger. When the compliance of the
. L$ C$ v$ c2 K8 |used lamp and the built-in lampholder were checked with the relevant requirements of IEC 60432-1
, t4 K# P; O+ band IEC 60238, they were found as satisfied. But the live part accessibility within the luminaire was
! Y* Q) c4 _/ d5 X" Vcaused by such a metal part projected from the lamp cap which is acceptable according to the sub clause

than 3 mm from the surface of the cap. See figure 1”. In this case there can easily come into existence a
