Parts that withstand the glow-wire test of IEC 60695-2-11, but which, during the test, produce # V( Q2 l; Z5 i# M# b9 O) N
a flame that persists for longer than 2 s, are further tested as follows. Parts above the 5 B1 b- V4 M& `; ? R
connection within the envelope of a vertical cylinder having a diameter of 20 mm and a height 7 c2 ]- ^5 b$ e8 ~) c8 \
of 50 mm are subjected to the needle-flame test of annex E. However, parts shielded by a

The needle-flame test is not carried out on parts of material classified as V-0 or V-1 according # {1 H# X) G! ^4 I# b) J& e
to IEC 60695-11-10, provided that the test sample was no thicker than the relevant part. . T" F! Y- Z2 i
