This standard specifies the test methods for the critical rise rate of commutation voltage and on-state surge current of bidirectional three-pole thyristors. The test methods and requirements for the general electrothermal characteristics and ratings of bidirectional three-pole thyristors should comply with the relevant standards. This standard is applicable to the testing of bidirectional three-pole thyristors.
