4.7.201.5 

Testing of printed boards 

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 material of printed 
boards, on which the available apparatus power 
at a connection exceeds 15 VA operating at a 
voltage exceeding 400 V (peak) a.c. or d.c. under 
normal operating conditions, and base material of 
printed boards supporting 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. 

NOTE – Available apparent power is the 
maximum apparent 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.

6.2.2 

Add the symbol NZ in the right hand margin 
beside the first paragraph. 

Add the following after the first paragraph: 

In Australia (this variation does not apply in New 
Zealand), compliance with 6.2.2 shall be checked 
by the tests of both 6.2.2.1 and 6.2.2.2.

6.2.2.1 

Add the symbol NZ in the right hand margin 
beside the first paragraph including Note 1. 

Delete Note 2 

Add the following after the first paragraph: 

In Australia (this variation does not apply in New 
Zealand), the electrical separation is subjected to 
10 impulses of alternating polarity, using the 
impulse test generator of annex N for 10/700µs 
impulses. The interval between successive 
impulses is 60 s and the initial voltage, Uc, is: for 
6.2.1 a):7.0 kV for hand-held telephones and for 
headsets and 2.5 kV for other equipment; and for 
6.2.1 b) and 6.2.1 c):1.5 kV. 

NOTE 201 – The 7 kV impulse simulates lightning 
surges on typical rural and semi-rural network 
lines. 

NOTE 202 – The value of 2.5 kV for 6.2.1 a) was 
chosen to ensure the adequacy of the insulation 
concerned and does not necessarily simulate 
likely overvoltages.

Add the following after the second paragraph: 

In Australia (this variation does not apply in New

for 6.2.1 b) and 6.2.1 c): 1.5 kV. 

NOTE 201 – Where there are capacitors across 
the insulation under test, it is recommended that 
d.c. test voltages are used. 

NOTE 202 – The 3 kV and 1.5 kV values have 
been determined considering the low frequency 
induced voltages from the power supply 
distribution system.

Canada and the United States of America have 
adopted a single, bi-national standard, CAN/CSA- 
C22.2 No. 60950-1/UL 60950-1, 

First Edition, which is based on IEC 60950-1, 
First Edition. Effective April 1, 2003, this standard 
may be used for product certification immediately, 
however, the previous version of the standard 
may also be used until April 1, 2005. 

Note: The previous version is CAN/CSA-C22.2 
No.60950-00/UL 60950 Third Edition, based on 
IEC 60950, 3rd Edition. Refer to the 

“IEC 60950, 3rd Edition, CA” section of this CB 
bulletin for the national differences in this version 
of the standard. 

This bi-national standard should be consulted for 
further details on the Special National Conditions 
and Other Differences summarized below. 

 P 

 

SPECIAL NATIONAL CONDITIONS 

 

 

Those requirements are identified as Special 
National Conditions since they are directly related 
to the Canadian Electrical Code (CEC), Part 1 
and the Canadian Building Code, which are 
referenced in legislation and which form the basis 
for the rules and practices followed in electrical 
and other building installations in Canada. 

Notes: 

- “CEC” denotes Canadian Electrical Code. 

- “NEC” denotes US National Electrical Code. 

- Due to common Canadian and US national 
differences, products that are in compliance with 
the Canadian national differences are also 
considered in compliance with the US national 
differences.
