Pressure Equipment Calculator

How do I find out the PED risk category for my pressure equipment or assembly?

Our Pressure Equipment Calculator is the fastest tool to determine the risk category according to the EU Pressure Equipment Directive (PED).

To use our 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 the category is determined, the conformity assessment regime (module) can be selected. You can find out more about the modules and manufacturer responsibilities on our PED modules explained page.
