The Directive: PED 97/23/EC
PED 97/23/EC (Pressure Equipment Directive) adopted by the European Parliament and the European Council on May 29, 1997 was published on May 29, 2002. Previously, manufacturers of pressure equipment could decide if the product would meet the Pressure Equipment Directive requirements or continue applying the existing national legislation. On May 29, 2002, the PED was made obligatory throughout the European Economic Area.
The main aim of the Pressure Equipment Directive is to harmonize the European national legislations with regards to the design, manufacture, testing and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar gauge. Pressure equipment can be represented by piping, vessels, safety accessories and pressure accessories. Assemblies means several pieces of pressure equipment assembled to form an integrated whole.
The directive arises from the “New Approach to Technical Harmonization and Standards” allowing for a flexible regulatory environment, without technical barriers to trade.
