NOTE 2 – The 3 kV and 1.5 kV values have been
determined considering the low frequency
induced voltages from the power supply
distribution system.
Annex YY Variations
YY.1
Parts of non-metallic material shall be resistant to
ignition and spread of fire.
This requirement does not apply to decorative
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
Components that are contained in an enclosure
having a flammability category of FV-0
according to AS/NSZ 4695.707 and having
openings only for the connecting wires filling
the openings completely, and for the
ventilation not exceeding 1 mm in width
regardless of the 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 1750 mm
3
,
integrated circuits, transistors and
optocoupler packages, if these components
are mounted on material 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 is checked by the tests of YY.1.1
Compliance is checked by the tests of YY.1.1

For the base materials of printed boards,
compliance is checked by the test of YY.1.3.
The tests are carried out on parts of non-metallic
The tests are carried out on parts of non-metallic
material, which have been removed from the
apparatus. When the glow-wire test is carried
out, they are placed in the same orientation, as
they would be in normal use.
These tests are not carried out on internal wiring.
