The Pressure Equipment Directive (PED) is a new approach directive that specifically covers equipment designed to contain a fluid (gas or liquid) at a pressure greater than 0.5_barg.  New approach directives were developed to enable free trade of consumer goods through the EU. However their application to complex pressurised equipment can cause major problems because they place the whole responsibility of not only design and manufacture, but also full hazard analysis solely on the manufacturer.

CE marks are applied by the manufacturer and require no registration, qualification, accreditation or liability insurance.
