DIN EN ISO 4126-6:2014-10

This International standard gives guidance on the application, selection and installation of bursting disc safety devices used to protect pressure equipment from excessive pressure and/or excessive vacuum. Annex A provides a checklist for the information to be supplied by the purchaser to the manufacturer. Annex B gives guidance on the replacement period of a bursting disc. Annex C provides guidance for determining the discharge capacity, for single phase fluids, of a pressure relief system that contains a bursting disc safety device. Annex D is a non-mandatory procedure for establishing the flow resistance of a burst bursting disc assembly. Annex E is a non-mandatory procedure for type testing of bursting disc safety devices. Annex F provides typical performance characteristics for various bursting disc safety device types. This document has been prepared by Technical Committee ISO/TC 185 "Safety devices for protection against excessive pressure" in collaboration with Technical Committee CEN/TC 69 "Industrial valves". The responsible German Working Committee is NA 003-01-10 AA "Sicherheitseinrichtungen gegen Drucküberschreitungen" ("Safety devices for the prevention of excessive pressure") at DIN.
