Scope and object This International Standard deals with impulse puncture testing in air of ceramic and glass insulator units of class B (see IEC 60383-1): cap and pin@ pin type (including pin-post type) and class B long rod insulators. This standard may be applied also in tests on Class B insulators of other materials (e.g. polymers and composites). However@ it may be useful to consider the possible need to adjust the test procedure accordingly. This standard is published with the object of specifying a standard procedure for impulse voltage puncture tests on insulators in air. Both type and sample test procedures are given.
