The needle-flame test shall not be carried out on
parts of material classified as V-0 or V-1
according to IEC 60695-11-10, provided that the
sample tested was not thicker than the relevant

4.7.201.4 Testing in the event of non-
extinguishing material
If the parts, other than enclosures, do not
withstand the glow-wire tests of 4.7.201.3, by
failure to extinguish within 30 s after the removal
of the glow-wire tip, the needle-flame test
detailed in 4.7.201.3 shall be made on all parts of
non-metallic material which are within a distance
of 50 mm or which are likely to be impinged upon
by flame during tests of 4.7.201.3. Parts shielded
by a separate barrier which meets the needle-
flame test need not be tested.

4.7.201.5 Testing of printed boards
The base material of printed boards shall be
subjected to the needle-flame test of Clause
4.7.201.3. The flame shall be applied to the edge
of the board where the heat sink effect is lowest
when the board is positioned as in normal use.
The flame shall not be applied to an edge,
consisting of broken perforations, unless the edge
is less than 3 mm from a POTENTIAL IGNITION
SOURCE.

Compliance shall be determined using the
smallest thickness of the material.
