Routine Tests:
Tests are carried out on each cable to check the requirements which are likely to vary during production.

Type Tests:
Tests are carried out to prove conformity with the specification. These are intended to prove the general qualities and design of a given type of cable.

Acceptance Tests:
Tests are carried out on samples taken from lot of the purpose of acceptance of the lot.

Optional Tests:
Special tests to be carried out when required by agreement between purchaser and us.
