Introduction Rupture Disc | Pressure Relief |
If a rupture disc type has a burst tolerance of +/-10%, and the defined burst pressure is 1 bar, the rupture disc will open between 900 mbar and 1.1 bar. Depending on the valid or applied rules and regulations the burst tolerance is at +/-10% (e.g. Pressure Equipment Directive 2014/68/EC), or +/-5% (e.g. ASME section VIII, Division 1), or +/-3% for very high burst pressures.
