BS EN ISO 4126-6:2003 Safety devices for protection against excessive pressure. Application, selection and installation of bursting disc safety devices
BS EN ISO 4126-6 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 and annex C guidance on determining the mass flow rate, for single phase fluids, of a pressure relief system that contains a bursting disc safety device
Annex E is a non-mandatory procedure for establishing the flow resistance of a burst bursting disc assembly.
The requirements for the manufacture, inspection, testing, marking, certification and packaging of bursting disc safety devices are given in BS EN ISO 4126-2.
