Pressure Equipment Directives
The Pressure Equipment Directive (PED) applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar gauge including vessels, piping, safety accessories and pressure accessories.
Not all pressure equipment is covered by this directive as The Transportable Pressure Equipment Directive and the Simple Pressure Vessels Directive both cover certain equipment and products which present a relatively low hazard from pressurization. These may be covered by other directives, e.g. Machinery Equipment Directive, ATEX Directive, Low Voltage Directive or the Electro Magnetic Compatibility Directive.
The Pressure Equipment Directive (PED) is European Legislation aimed at removing the technical barriers to trade relating to the supply of pressure equipment throughout Europe.
PED covers all types of fixed equipment:
- Pressure Vessels
- Piping
- Steam Generators
- Pressure Accessories
- Safety Accessories
- Assemblies comprising two or more items listed above
PED does NOT cover the following types of equipment (with conditions):
- Conveyance pipelines
- Water supply networks
- Military Equipment
- Nuclear equipment
- Well control equipment
- Equipment not specifically designed for pressure such as IC engines and turbines
- Pressure equipment installed on ships, rockets, aircraft, and mobile offshore units
- The justification for the above exemptions range from low risk to existing legislative regulations
