22、20003 Introduction This part of IEC 243 is one of a series which deals with tests for electric strength of solid insulating materials. The series will consist of four parts: Part 1: Tests at power frequencies; (IEC 243-1) Part 2: Additional requirements for tests using direct voltage; (IEC 243-2) Pa
23、rt 3: Additional requirements for impulse tests; (IEC 243-3) Part 4: Statistical treatment and interpretation. (IEC 243-4) (under consideration) 1 Scope This part of IEC 243 gives requirements, additional to those in IEC 243-1, for the determination of the electric strength of solid insulating mater
24、ials under impulse voltage stress. NOTEThis part is based upon ASTM Method D3426, to which it is intended to be technically identical. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of IEC 243.
