Testing is carried out during every stage of manufacture of all
cables.

Designing electrical power distribution systems requires considerable
expertise and experience. The calculations and decisions that
are made result in the selection of a specific cable, and require
that such a cable be manufactured to very definite and rigid specifications.
The specifications ensure that the cables will perform to the
design requirements efficiently and safely.
In Canada, the standards for the design and testing of medium-voltage
cables are the applicable requirements of CSA, AEIC, IEC and the
ICEA.
Raw materials used in the manufacture of the cables, are subject
to quality control and evaluation tests. They consist of a variety
of physical, mechanical, electrical and chemical tests, usually
governed by the material purchasing specifications of the wire
and cable company and ASTM Standards.
Testing is carried out during every stage of manufacture of a
cable, and upon completion, the routine tests that would be carried
out on each length of cable may include conductor resistance,
high-voltage time tests, spark test of the jacket, and dimensional
measurements of components.
