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. 
No TNV provided.

6.2.2.2 
Add the symbol NZ in the right hand margin beside 
the second paragraph.

Add the following after the second paragraph: 
In Australia (this variation does not apply in New 
Zealand), the a.c. test voltage is: 
for 6.2.1 a):3 kV; and 
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. 
No TNV provided.

Canada and the United States of America have adopted a single, bi-national 
standard, CAN/CSA C22.2 No. 60950-1/UL60950-1, 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 nationa l 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. 
 
 
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. 
 
1.1.1  
All equipment is to be designed to allow 
installation in accordance with the National 
Electrical Code (NEC), ANSI/NFPA 70, the 
Canadian Electrical Code (CEC), Part I, 
CAN/CSA C22.1, and when applicable, the 
National Electrical Safety Code, IEEE C2. 
Also, unless marked or otherwise identified, 
installation is allowed per the Standard for the 
Protection of Electronic Computer/Data-
Processing Equipment, ANSI/NFPA 75. 
Class III equipment. 
N/A 
1.4.14 
For pluggable Equipment Type A, the 
protection in the installation is assumed to be 
20A.

N/A 
1.5.5  
For lengths exceeding 3.05 m, external 
interconnecting flexible cord and cable 
assemblies are required to be a suitable cable 
type (e.g. DP, CL2) specified in the NEC.  
For length 3.05m or less, external 
interconnecting flexible cord and cable 
assemblies which are not types specified in the 
NEC are required to have special construction 
features and identification markings. 
The interconnecting cables contain 
only SELV.
