) above and 1.5 kV DC . It defines the procedures for four primary types of tests:

The standard switching impulse is now defined as 170/2500 µs , with the term "front time" replacing the older "time-to-peak" to align with lightning impulse terminology. To ensure test results are "recognized and defensible,"
