Application Summary AI generated
This standard specifies the testing methods for detecting internal and surface flaws, such as cracks, pores, and delamination, in copper-tungsten (Cu-W) electrical contacts. It is applied in the manufacturing and quality control of high-voltage switchgear, circuit breakers, and other electrical apparatus where Cu-W contacts are used to ensure reliable performance under arcing and high-temperature conditions. The standard provides procedures for ultrasonic and other nondestructive testing techniques to verify contact integrity before installation or during maintenance.
