The Pressure Equipment Directive 2014/68/EU, known as PED (Pressure Equipment Directive), is a product directive issued by the European Union, which regulates the design, manufacture and conformity assessment of pressure equipment and assemblies.
The PED 2014/68/UE applies to vessel, piping, safety accessories, pressure accessories and assemblies subjected to a maximum allowable pressure PS greater than 0.5 bar.
Pressure equipments, with a pressure equal to or less than 0.5 bar, are excluded from the application of the Directive.
Pressure equipment, which fall within the scope, must meet the Essential Safety Requirements defined in Annex I of the PED.
When placing on the market, manufacturers shall affix the CE marking and issue the EU declaration of conformity.
The PED identifies manufacturers as responsibles for the construction, with the intervention of the Notified Body for the conformity assessment in the foreseen cases.
The PED only concerns the placing on the EU market of pressure equipment, but it does not give indications about the requirements related to the operation and maintenance of the same, which are defined by National Regulations.
The PED requires manufacturers to identify the danger category of the equipment built, which is linked to the concept of energy stored in the equipment. The energy stored is evaluated based on the following parameters:
Annex II defines, through 9 tables, the belonging of the component or of the equipment to one of the four risk categories, with reference to the type of pressure equipment, to the group and to the physical state of the fluid, to the PSxV value in the case of vessel and PSxDN in the case of pipes .
The category of the assemblies is determined by the highest category of components, excluding safety accessories.
ECO works as Notified Body nr. 0714 for the conformity assessment of Pressure Equipments according to the following procedures defined by the PED:
On request, ECO, during the testing phase, performs the inspection of safety devices efficiency as required by the Italian Ministerial Decree n. 329 of 01/12/2004 – art. 5, paragraph D – which exempts the user from requesting inspection of commissioning by INAIL (National Institute for Insurance against Workplace Accidentals and Occupational Disease).
