Publication date:   Jan 1, 1981

Scope

Defines terms of insulation co-ordination and valve construction. Describes methods for type tests carried out to verify that the valve design will meet the specified requirements. Covers production tests carried out to verify proper manufacture. Production tests consist of routine tests (on all valves, modules or components) and sample tests (on a small number taken at random from a batch). Appendix gives guidance for the choice of test safety factor.
