Scope:
When conformance tests are required, this standard specifies tests to demonstrate that the circuit breaker being tested conforms with the ratings assigned to it in accordance with ANSI/IEEE C37.04. Preferred ratings are listed in ANSI C37.06. As a requirement of conformance testing, the circuit breaker shall have completed the design testing requirements of ANSI/IEEE C37.09. If ANSI/IEEE C37.09 tests have not been previously performed, the tests required by ANSI/IEEE C37.09 beyond tests described by this standard may be performed concurrently with conformance testing.
NOTE—Additional tests per ANSI/IEEE C37.09 need not be witnessed by the certifying party.
