Insulators of ceramic material or glass for overhead lines with a nominal voltage greater than 1000 V. Impulse puncture testing in air Ingestion-build-61878 Contents of BS EN 1570:What is BS EN 61211 Impulse puncture testing in air for ceramic material insulators about? BS EN 61211 deals with impulse puncture testing in air of ceramic and glass insulator units of class B: cap and pin, pin type (including pin post type) and class B long rod insulators. BS EN 61211 is applied also in tests on Class B insulators of other materials (e. g. polymers and composites). However, it is useful to consider the possible need to adjust the
