The PED embraces all Pressure Equipment subject to an internal pressure of gas or liquid above 0.5 bar. It applies to new Equipment fabricated in the EU (and to new or used Equipment imported from countries outside the EU). In-service inspection of operating equipment is covered in the national regulations of each EU country. (It is not intended to develop an EU Directive covering in-service inspection.) All materials, metallic and nonmetallic, are considered. This scope is very wide as it covers any pressure containment above 0.5 bar from simple pressure- cookers to large water-tube boilers.
