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.
