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

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 glow-wire test cannot be carried out, such

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

relevant part.
4.7.201.4 Testing in the event of non-extinguishing material If
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 the tests of 4.7.201.3. Parts
shielded by a separate barrier which meets the needle-flame
test
need not be tested.
NOTE 1 - If the enclosure does not withstand the glow -wire test
the equipment is considered to have failed to meet the
requirements of Clause 4.7.201 without the need for
consequential testing.
NOTE 2 - If other parts do not withstand the glow-wire test due
to ignition of the tissue paper and if this indicates that burning
or glowing particles can fall onto an external surface
underneath the equipment, the equipment is considered to
have failed to meet the requirements of Clause 4.7.201 without
the need for consequential testing.
NOTE 3 - Parts likely to be impinged upon by the flame are
considered to be those within the envelope of a vertical cylinder
having a radius of 10 mm and a height equal to the height of

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.
The test is not carried out if the — Printed board does not carry
any POTENTIAL IGNITION SOURCE; Base material of printed
boards, on which the available apparent power at a connection
exceeds 15 VA operating at a voltage exceeding 50 V and equal
or less than 400 V (peak) a.c. or d.c. under normal operating
conditions, is of flammability category FV-1 or better according
to AS/NZS 4695.707, or the printed boards are protected by an
enclosure meeting the flammability category FV-0 according to
AS/NZS 4695.707, or made of metal, having openings only for
connecting wires which fill the openings completely; or Base

spark gaps which provides protection against overvoltages, is
of flammability category FV-0 according to AS/NZS 4695.707 or
the printed boards are contained in a metal enclosure, having
openings only for connecting wires which fill the openings
completely. Compliance shall be determined using the
smallest thickness of the material.

power which can be drawn from the supplying circuit through a
resistive load whose value is chosen to maximise the apparent
power for more than 2 min when the circuit supplied is
disconnected.
