Pressure Equipment Directive |

| › Pressure Equipment Directive |
|
| Background |
The Pressure Equipment Directive (PED) was adopted by the European Institutions in 1997, and became mandatory in May 2002.
The PED sets the legislative framework for equipment subject to a pressure hazard. It regulates the design, production, testing, and marking of pressure equipment and assemblies with a maximum allowable pressure PS greater than 0.5 bar. The purpose is to ensure that safety issues are considered during the design process of this type of equipment.

 |
|
The PED was designed to remove trade barriers within the EU through technical harmonization of national standards. The Directive does not, however, impose any detailed technical solution, thereby promoting the development of new technologies to meet the requirements.
|
| Impact on Refrigeration & Heat Pump Systems |
Under the framework of the Pressure Equipment Directive, several standards for refrigerating and heat pump systems have been established. Vessels, valves, piping, pressure relief devices, pressurized storage containers and heat exchangers, among others, are covered by its scope. The European Committee for Standardization (CEN) is the responsible body for developing standards for pressure equipment in refrigerating and heat pump systems.
|
| Targets |
To meet the PED requirements, pressure equipment and assemblies must:
- Satisfy conformity assessment procedures
- Bear the CE marking
|
| Official documents |
|
| Latest & Next steps |
To ensure a coherent application of the Directive, a working group is developing a set of guidelines. The group, composed of experts from EU Member States and Standardisation organisations, meets regularly to keep progress in the setting up and updating of these guidelines.
