ZZ.1 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. 
ZZ.2 Variations 
The variations are as follows: 
1.2 
Between the definitions for ‘Person, service’ and 
‘Range, rated frequency’ insert the following: 
POTENTIAL IGNITION SOURCE
 1.2.12.201
Class III equipment, powered 
from a LPS adaptor evaluated in 
this test report. (refer to 
summary of testing) 
N/A 
1.2.12.15 
After the definition 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.
Class III equipment. 
N/A 
1.5.1 
Add
 the following to the end of first paragraph: 
‘or the relevant Australian/New Zealand 
Standard’. 
All critical components are IEC, 
UL or CSA certified. 
1.5.2 
Add
 the following to the end of first and third dash 
items: 
‘or the relevant Australian/New Zealand 
Standard’. 
All critical components are IEC, 
UL or CSA certified.

complying with AS/NZS 3112, shall comply with 
the requirements in AS/NZS 3112 for equipment 
with integral pins for insertion into socket-outlets.
Not direct plug-in equipment.

Report No.  116366 
 
 
 
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: 
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
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 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.
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.
 
All materials have suitable flame 
class, no testing required.

Report No.  116366 
 
 
 
4.7.201 
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 not be 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 also be carried out on other parts of 
insulating material which are within a distance of 3 
mm 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: 
All materials have suitable flame 
class, no testing required.
