POTENTIAL IGNITION SOURCE:
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.

Parts of non-metallic material shall be resistant to
Parts of non-metallic material shall be resistant to
ignition and spread of fire.
This requirement does not apply to decorative
trims, knobs and other parts unlikely to be ignited
or to propagate flames originating from inside the
apparatus, or the following:
a) Components that are contained in an enclosure
having a flammability category of FV-0 according
to AS/NZS 4695.707 and having openings only for
the connecting wires filling the openings
completely, and for ventilation not exceeding 1
mm in width regardless of length.
b) The following parts which would contribute
negligible fuel to a fire:
- small mechanical parts, the mass of which does
not exceed 4 g, such as mounting parts, gears,
cams, belts and bearings;
- small electrical components, such as capacitors
with a volume not exceeding 1750mm

NOTE: In considering how to minimize propagation of fire and
what ‘small parts’ are, account should be taken of the
cumulative effect of small parts adjacent to each other for the
possible effect of propagating fire from one part to another.

Compliance shall be checked by the tests of
4.7.201.2, 4.7.201.3, 4.7.201.4 and 4.7.201.5.
For the base material of printed boards,

The tests shall be carried out on parts of non-
metallic material which have been removed from
the apparatus. When the glow-wire test is carried
out, the parts shall be placed in the same
orientation as they would be in normal use.
These tests are not carried out on internal wiring.
