The Pressure Equipment Directive requires a manufacturer to determine its pressure equipment’s PED category.
To use this free calculator, select from piping, vessel, or steam generator. The maximum allowable pressure and either the vessel volume or pipe diameter are then required. You also need to give the fluid state (liquid or gas) and the fluid group.
Once you have ascertained the PED category, you can choose an appropriate conformity assessment procedure.
