Scope and Objectives

When conformance tests are required, this standard specifies tests to demonstrate that the circuit breaker being tested conforms with the ratings assigned to it by the manufacturer in accordance with IEEE C37.04. Preferred values of the ratings are listed in clause 6 of IEEE C37.04; other values may be assigned to the circuit breaker by the manufacturer where supported by a complete set of type tests supporting these alternative values. Conformance tests according to this standard must utilize the assigned rated values from the type testing. As a requirement of conformance testing, the circuit breaker shall have completed the design testing requirements of IEEE C37.09. If IEEE C37.09 tests have not been previously performed, the tests required by IEEE C37.09 beyond tests described by this standard may be performed concurrently with conformance testing.

Note: Additional tests per IEEE C37.09 need not be witnessed by the certifying party.
