Pressure Equipment CE Marking and UKCA Marking

Our Offer to you:

We will help you with:

  • Applying the Pressure Equipment Directive (PED) and workplace safety directives to your products
  • Identifying the applicable standards and providing risk assessment checklists and other materials
  • Carrying out compliance inspections, design reviews and risk assessments according to general and product-specific standards
  • Global Conformity Assessment of pressure assemblies and systems according to PED article 14 section 6
  • Compling appropriate technical files
  • Choosing and managing Notified Body or UK conformity assessment body and preparing technical documentation for submission• Completing declarations of conformity
  • Representing pressure equipment as the responsible economic operator in the EU and UK through our sister company Authorised Rep Compliance Ltd.


The Pressure Equipment Directive 2014/68/EU sets out a single set of rules that pressure equipment and assemblies must comply with to be placed on the market, used and moved freely in the EU. It continues to apply in the Great Britain because the EU Withdrawal Act retained The Pressure Equipment (Safety) Regulations 2016 as UK domestic legislation when the UK left the EU.
The Pressure Equipment Directive replaced a variety of different commercial and member state certification schemes for pressure equipment that were barriers to trade preventing an EU single market.


The Pressure Equipment Directive covers pressure equipment such as accessories, components and assemblies.

The meanings of these terms define the scope:

  • pressure equipment such as vessels and piping assemblies
  • pressure accessories (like valves and gauges)
  • safety accessories (like safety valves)
  • assemblies built by a manufacturer for an end user but not those built by end users for their own use (which are referred to as installations.)

Tubing and fittings used to make piping assemblies are treated like materials such as boiler plate – They are not required to be CE marked but there are standards to allow the pressure equipment made from these materials to be CE or UKCA marked;

Equipment on the lowest risk category, SEP, can be placed on the market as long as it is designed and manufactured according to Sound Engineering Practice and without meeting the more complicated Essential Requirements.

Equipment in the Lowest two categories SEP and I is excluded from the PED if it is covered by another CE marking safety directive such as the Machinery Directive.


Assemblies must be CE-marked to show that they are properly integrated, protected from exceeding the maximum allowable pressure, temperature, etc. and safe to use. This is called the Global Conformity Assessment procedure and is required even if all the equipment in the assembly is already CE-marked.


Diagrams in PED Annex II (called tables) divide products into five risk categories depending on the size and working pressure, type of equipment (vessel, piping or boiler) and hazard of the contents. The requirements increase in proportion to the category and hazard from a simple set of rules to follow for the lowest Sound Engineering Practice category to third party certification of compliance with all design and manufacturing requirements for the highest risk equipment in Category IV.


Before placing products on the market, manufacturers must:

  • ensure they meet the directive’s Essential Health and Safety Requirements usually by following EN standards.
  • compile and keep a technical file demonstrating compliance
  • follow the relevant certification procedure and get the required third-party certificates
  • issue an EU or UK Declaration of Conformity.
  • apply the CE conformity marking (or UKCA marking in Great Britain) as well as other specified markings.

The PED’s Essential Requirements set out requirements for hazard assessment, materials, design, manufacture, testing and inspection, markings and instructions. Harmonised standards describe in detail how to apply the essential requirements to different products.

Harmonised standards explain how to apply the essential requirements to most materials, equipment, manufacturing techniques and some assemblies. The use of national and overseas codes such as ASME and former British and European national standards is relatively common because the complexity makes it easier to show how these meet the Essential Requirements than to change to European Standards.

EU Use of Work Equipment Directive / PSSR

After it is put into service, Pressure equipment and systems and other equipment in workplaces must comply with the Use of Work Equipment Directive 2009/104/EU. This directive is closely related to the PED and other CE marking directives and uses their essential requirements as the safety benchmark for equipment in service. It is more commonly known by the name of implementing regulations in European countries such as The Pressure Systems Safety Regulations (PSSR) in the UK.

As well as requiring pressure systems to be safely designed manufactured, installed, operated, controlled and maintained, it has a strong emphasis on periodic examinations to be specified and completed by a competent person and records to be kept.
