Pressure Equipment Directive

Table of Contents


The Directive applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar.

Vessels, piping, safety accessories and pressure accessories are all included.

Typical examples of pressure equipment covered include:

  • shell and water tube boilers
  • heat exchangers
  • pressure vessels
  • process pipework
  • electric heaters
  • valves - isolation
  • valves - control
  • meters
  • relief valves
  • safety valves
  • bursting discs
  • buckling rods
  • controlled safety pressure relief systems
  • pressure switches
  • temperature switches
  • fluid level switches

The Directive (art.13) classifies a few categories for pressure equipment, based on:

  • hazard level, which is determined based on stored energy (pressure-volume product)
  • nature of the contained fluid.

The Directive does not apply to:

  • assembly of pressure equipment on site and under the responsibility of the user, as in the case of industrial installations;
  • equipment for military use, for use in transport;
  • equipment which presents a relatively low hazard from pressurization and which is within the scope of another CE mark directive (e.g. the Machinery Directive, Atex Directive, Low Voltage Directive, Medical Lift, )
  • vessels used for the transport of fluids while under pressure (i.e. containers used for the transport of fluids by road, rail, sea and air). These are subject to another directive, the Trans-portable Pressure Equipment Directive (TPED);
  • simple pressure vessels, which are the subject of a separate directive;
  • aerosol dispenser;
  • several classes of equipment as set out in the article 1.2 of the PED 2014/68;

The Directive: PED 2014/68/EU

The new Pressure Equipment Directive (PED) 2014/68/EU of the European Parliament and of the Council on the market of pressure equipment replaces the former Pressure Equipment Directive 97/23/EC as from 19th July 2016.

The Pressure Equipment Directive (PED) applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure (PS) greater than 0.5 bar.

The purpose of the PED is to ensure common standards of safety in all pressure equipment sold within the European Economic Area. Manufacturers are therefore able to meet the requirements for approval in any member state of the EU, and do not have to repeat the process when selling goods in any other state.

• Chapter I: General Provisions (Art. 1-5)

• Chapter II: Obligations of Economic Operators (Art. 6-11)

• Chapter III: Conformity and classification of PED and assemblies (Art.12- 19)

• Chapter V: Notification of Conformity Assessment bodies (Art.20- 43)

• Chapter VI: Committee Procedure and delegated acts (Art.44- 46)

• Chapter VII: Transitional and Final Provisions (Art.47- 52)

• Annex I: Essential Safety Requirements

• Annex II: Conformity Assessment Tables

• Annex III: Conformity Assessment Procedures

• Annex IV: EU Declaration of Conformity

Path to EU Market Entry: Compliance

Assessment and conformity procedure are different for each category, in which the equipment is classified (Art.14):

Essential Safety Requirements

The Annex I of the Directive defines certain safety requirements about the design and perfor-mance of pressure equipment, such as:

- equipment must be designed for adequate strength taking into account internal/external pres-sure, ambient and operational temperatures, static pressure and mass of contents in operating and test conditions, traffic, wind, earthquake loading, corrosion and erosion, fatigue, decomposi-tion of unstable fluids;

- it must be ensured safe handling and operation of examination;

- adequate means shall be provided for the draining and venting of equipment;

- equipment must be provided with protection against exceeding the allowable limits of pressure;

- where necessary, pressure equipment must be designed and fitted with suitable accessories to meet damage-limitation requirements in the event of external fire;

Specific requirements are defined for materials used for the manufacturer of pressure equipment.

Harmonized Standard

Pressure equipment or assemblies, which are in conformity with harmonized standards or parts thereof, which have been published in the Official Journal of the European Union, shall be presumed to be in con-formity with the essential safety requirements covered by those standards or parts thereof, referred to in Annex I.

The materials used for the manufacture of pressure equipment or assemblies which are in conformity with European approvals for materials, the references of which have been published in the Official Journal of the European Union, shall be presumed to be in conformity with the applicable essential safety requirements set out in Annex I.

There is a special category of pressure equipment and assemblies - below or equal to the limits set out in all the other categories - which must be designed and manufactured in accordance with the Sound Engineer-ing Practice (SEP) of a Member State to ensure safe use.

The Essential Safety Requirements of the Directive do not apply to product falls in the SEP category but can be a good guidance in absence of other instructions. A derogation it is also made for the CE marking of SEP, since Article 4 paragraph 3 explicitly prohibits CE marking of SEP pressure equipment.

Technical Documentation

The manufacturer shall draw up the technical documentation referred to in Annex III of the Directive.

Authorized Representative

At the discretion of the manufacturer, an Authorized Representative may be appointed by written mandate to undertake such activities as:

  • Keeping the Declaration of Conformity and the technical documentation available to the Competent Authorities at all times and for 10 years after the equipment is placed on the market
  • Accommodate any reasoned requests from the Competent Authorities relating the documentation or conformity of the pressure equipment
  • Cooperate with the Competent Authorities regarding and actions to be taken to eliminate and risks relate to the pressure equipment for which they are responsible under the mandate

The Authorized Representative should be clearly identified on the packaging to ensure efficient communication from end-users and EU economic operators in regards to the product(s) compliance.

The authorized representative may not draw up technical documentation as referred to in Article 6(2).

For non-EU manufacturers: Appoint a European Authorized Representative established within the European Community.

Post-Marketing Surveillance

Traceability of the pressure equipment and assemblies should be guaranteed throughout the whole process in order to make market surveillance systematic and efficient for market surveillance authorities.

Risks of Non-Compliance

The directive portrays European Law in forced within the European Economic Area (EEA); non-compliance with the directive’s requirements will result in the removal of the product from the market and the revoking of the CE marking affixed on the equipment.

The non-compliance with the Directive’s requirements will result in the removal of the equipment from the market and the revoking of the CE marking affixed on it.
