scope:

This test code summarizes the various tests which may be made on power circuit breakers and describes accepted methods used in making these tests. These tests may be divided into two classifications:

(a) Design Tests

(b) Production Tests

Design Tests.

Design tests are those tests made to determine the adequacy of the design of a particular type, style, or model power circuit breaker to meet its assigned ratings and to operate satisfactorily under normal service application conditions, or under special conditions if specified. Design tests are made only on representative breakers to substantiate the ratings assigned to all other breakers of similar design and are not contemplated in normal production.

Product├Čon Tests.

Production tests are those tests made to check the quality and uniformity of the workmanship and materials used in the manufacture of power circuit breakers.
