What is the Pressure Equipment Directive (PED)?

The Pressure Equipment Directive (PED) 2014/68/EU defines mandatory safety and conformity requirements for pressure equipment and assemblies with a maximum allowable pressure above 0.5 bar (7.25 psig) that are placed on the EU market. 

The Directive applies to a wide range of equipment, including: 

  • Pressure vessels and steam boilers 
  • Piping and pressure accessories 
  • Safety accessories 
  • Assemblies of pressure equipment 

Compliance with PED 2014/68/EU is essential for manufacturers, designers, and integrators to legally affix the CE marking and access the EU market. 

How TÜV SÜD can help you achieve PED compliance

PED compliance is achieved through a structured conformity assessment process, often involving a Notified Body, depending on equipment classification and risk. 

TÜV SÜD is an EU-accredited Notified Body for PED 2014/68/EU and supports you throughout the process. 

Key PED conformity assessment steps 

  • Fluid classification and hazard assessment 
    • Group 1: hazardous fluids (explosive, toxic, flammable) 
    • Group 2: non-hazardous fluids 
  • Pressure and stored energy evaluation 
    • Assessment of pressure, volume, nominal diameter, and stored energy 
  • PED category determination 
    • Classification into Category I, II, III, or IV based on risk 
  • Selection of conformity assessment module 
    • Modules such as A/A2, B+C2, B+D, B+F, G, H/H1 
  • Technical documentation and CE marking 
    • Preparation of technical files and Declaration of Conformity

Frequently asked questions (FAQ)

What types of equipment are covered by PED?

Equipment covered under the Pressure Equipment Directive (PED) includes pressure vessels, pressure accessories, piping, steam boilers, safety accessories, and assemblies that operate above 0.5 bar gauge pressure. 

Who must comply with PED?

The manufacturer is responsible for PED compliance. They must ensure the equipment meets all essential safety requirements, perform or coordinate conformity assessments, and provide the required technical documentation and CE marking before placing the product on the market. 

What documents are required for PED compliance?

To place pressure equipment on the EU market, manufacturers must ensure the CE marking is affixed and supported by complete documentation, including:

  • EU Declaration of Conformity 
  • Technical documentation and calculations 
  • Risk assessment records 
  • Quality system documentation (where applicable) 
How long does the certification process take?

The timeline varies depending on the complexity of the equipment and the conformity assessment procedure required. Factors such as design documentation, manufacturing stage, and notified body availability can influence the total timeline. 

Does PED 2014/68/EU also apply to the UK market?

PED 2014/68/EU applies to the EU market. For Great Britain, pressure equipment must comply with applicable UK regulations (UKCA). PED software may support reference to both EU and UK requirements, depending on project needs. 

Can PED software replace conformity assessment by a Notified Body?

No. PED software supports internal compliance activities such as classification, risk analysis, and documentation preparation, but it does not replace conformity assessment or certification by a Notified Body where required under PED.
