Pressure Equipment Directive

The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one litre in volume and having a maximum pressure more than 0.5 bar gauge. It also sets the administrative procedures requirements for the "conformity assessment" of pressure equipment, for the free placing on the European market without local legislative barriers. It has been mandatory throughout the EU since 30 May 2002, with 2014 revision fully effective as of 19 July 2016.

The Pressure Equipment Directive aims to guarantee free movement of the products in its scope while ensuring a high level of safety.
The implementation of the Directive is supported by a set of PED Guidelines and guidance documents:
Guidelines - pressure equipment directive 97/23/EC (related to the former PED)
Guidelines - pressure equipment directive 2014/68/EU
These guidelines are not legally binding – instead, they help to ensure that the directive is applied consistently.
