scope:
This part of ISO 4126 specifies requirements for safety valves. It contains information which is commn to ISO 4126-1 to ISO 4126-6 to avoid unnecessary repetition.
For flashing liquids or two-phase mixtures, see ISO 4126-10.
The user is cautioned that it is not recommended to use the ideal gas formula presented in 6.3when the relieving temperature is greater than 90% of the thermodynamic critical temperature and the relieving pressure is greater than 50% of the thermodynamic critical pressure. Additionally, condensation is not considered. If condensation occurs, the method presented in 6.3 should not be used.
