Variations to IEC 60950-1:2001 for application in Australia 
and New Zealand 

 P 

ZZ1 Introduction 

This Annex sets out variations between this Standard and IEC 
60950-1:2001. These variations indicate national variations for 
purposes of the IECEE CB Scheme and will be published in 
the IECEE CB Bulletin. These variations are indicated within 
the body of the Standard. 

 P 

ZZ.2 Variations 

The variations are as follows: 

CLAUSE 

 P 

1.2 

Between the definitions for ‘Person, service’ and 
‘Range, rated frequency’ insert the following: 

l ignition source 1.2.12.201 

 P 

1.2.12.15 

 

After the definition of 1.2.12.15, add the following:

1.2.12.201 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. 

NOTE 201 An electronic protection circuit may be 
used to prevent such a fault from becoming a 
POTENTIAL IGNITION SOURCE. 

NOTE 202 This definition is from AS/NZS 
60065:2003.

Add the following after Clause 4.7.3.6. 

4.7.201 Resistance to fire – Alternative tests 

 N/A 

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 mm

3

, 

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. 

 N/A 

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. 

The needle-flame test shall be made in 
accordance with AS/NZS 4695.2.2 with the 
following modifications:
