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:
A) A component certified by a Canadian or
U.S. 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 subjected to
the applicable tests of the equipment standard.
B) 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.
C) 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
