Rupture discs are regulated by several international standards that define design, manufacturing and testing:
- ASME Section VIII Div. 1 & Div. 2 – Boiler and Pressure Vessel Code (USA).
- API 520/521/2000 – Guidelines for pressure relief devices in the oil and gas industry.
- EN ISO 4126 – European/international series on safety devices for protection against excessive pressure.
- PED 2014/68/EU – Pressure Equipment Directive (CE marking).
- 3-A and ASME BPE – Hygienic requirements for food and bioprocesses where applicable.
Complying with the appropriate standards ensures acceptance by inspection bodies and compatibility with pressure relief valves and instrumentation systems.
