Possible fault which can start a fire if the open-
circuit voltage measured across an interruption or
faulty contact exceeds a value of 50 V (peak) a.c.
or d.c. and the product of the peak value of this
voltage and the measured r.m.s. current under
normal operating conditions exceeds 15 VA.

Such a faulty contact or interruption in an
electrical connection includes those which may
occur in conductive patterns on printed boards.
