Applies to a.c. circuit breakers within the scope of IEC 56 (clause 1). It provides the general rules for testing a.c. circuit breakers, for making and breaking capacities over the range of test duties described in Sub clauses 6.102 and 6.111 of Publication 56, by synthetic methods. The purpose of this standard is to establish criteria for synthetic testing and for the proper evaluation of results. Such criteria will establish the validity of the test method without imposing restraints on innovation of test circuitry.
