3 TERMS AND DEFINITIONS
For the purpose of this document, the terms and definitions given in GB/T 21437.1 apply.
4 TEST METHODS
4.1 General
This document describes three test methods for testing the immunity of electrical/electronic components [i.e., device under test (DUT)] against coupled electrical transient pulses, i.e., capacitive coupling clamp (CCC) method, direct capacitive coupling (DCC) method, and inductive coupling clamp (ICC) method. These tests shall be carried out in the laboratory.
