The following key national differences are based on requirements other than
national regulatory requirements. The bi-national standard (CAN/CSA C22.2 No.
60950-1/UL 60950-1, First Edition) referenced above should be consulted for
further details on the national differences summarized below.

1.5.1
Components of equipment must be suitable for
the application, and must comply with the
requirements of the equipment standard and
the applicable national (Canadian and/or U.S.)
component or material standards, as far as
they may apply.
The acceptance will be based on the following:
I) A component Certified by a Canadian or U.S.
National Certification Body (NCB) to a
Canadian or U.S. component standard will be
checked for correct application and use in
accordance with its specified rating. Where
necessary, it will also be subject to the
applicable tests of the equipment standard.
J) A component, which has a CB Test
Certificate for compliance with a relevant IEC
component standard, will be checked for
correct application and use in accordance with
its specified ratings. Where necessary, it will
also be subject to the applicable tests of the
equipment standard, and to the applicable
tests of the Canadian and/or U.S. component
or material standard, under the conditions
occurring in the equipment.
K) A component, which has no approval as in
A) or B) above or which is used not in
accordance with its specified ratings, will be
subject to the applicable tests of the equipment
standard, and to the applicable tests of the
Canadian and/or U.S. component or material
standard, under the conditions occurring in the
equipment.
L) Some components may require annual re-
testing, which may be carried out by the
manufacturer, CSA International or another
laboratory

2.3.1
For TNV-2 and TNV-3 circuits with other than
ringing signals and with voltages exceeding
42.4 Vp or 60 Vdc, the maximum acceptable
current through a 2000 ohm resistor (or
greater) connected across the voltage source
with other loads disconnected is 7.1 mA peak
or 30 mA dc under normal operating
conditions.
