4.7.201
Add the following after Clause 4.7.3.6.
4.7.201 Resistance to fire – Alternative tests
4.7.201.1 General
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:
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.
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 1 750 mm3, integrated circuits,
transistors and optocoupler packages, if these
components are mounted on material of flammability
category FV-1, or better, according to AS/NZS
4695.707.
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, compliance
shall be checked by the test of 4.7.201.5.
The tests shall be carried out on parts of non-
metallic material which have been removed from the
apparatus. When the glowwire 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.
4.7.201.2 Testing of non-metallic materials
Parts of non-metallic material shall be subject to the
glow-wire test of AS/NZS 60695.2.11 which shall be
carried out at 550°C. Parts for which the glow-wire
test cannot be carried out, such as those made of
soft or foamy material, shall meet the requirements
specified in ISO 9772 for category FH-3 material.
The glow-wire test shall be not carried out on parts
of material classified at least FH-3 according to ISO
9772 provided that the sample tested was not thicker
than the relevant part.
4.7.201.3 Testing of insulating materials
Parts of insulating material supporting POTENTIAL
IGNITION SOURCES shall be subject to the glow-
wire test of AS/NZS 60695.2.11 which shall be
carried out at 750°C.

The test shall be also carried out on other parts
of insulating material which are within a
distance of 3mm of the connection.
NOTE Contacts in components such as switch
contacts are considered to be connections.
For parts which withstand the glow-wire test
but produce a flame, other parts above the
connection within the envelope of a vertical
cylinder having a diameter of 20 mm and a
height of 50 mm shall be subjected to the
needle-flame test. However, parts shielded by
a barrier which meets the needle-flame test
shall not be tested.
