• The Pressure Equipment Directive (97/23/EC) was adopted by the European Parliament and the European Council in May 1997.
It initially came into force on 29 November 1999. From that date until 29 May 2002 manufacturers had a choice between applying the pressure equipment directive or continuing with the application of the existing national legislation.
From 30 May 2002 the pressure equipment directive is obligatory throughout the EU.
• The new PED Directive (2014/68/EU) was published in the Official Journal of the EU on 27th of June 2014. The new directive came into force on the 17th of April 2016 with no transitional period. Please contact us for the information on the changes of the new EMC directive.
Main requirements of the Directive:
Pressure equipment and assemblies above specified pressure and/or volume thresholds must:
• Be safe; meet essential safety requirements covering design, manufacture and testing;
• Satisfy appropriate conformity assessment procedures;
• Carry the CE marking and other information.
Pressure equipment and assemblies below the specified pressure / volume thresholds must:
• Be safe;
• Be designed and manufactured in accordance with the sound engineering practice of a Member State;
• Bear specified markings (but not the CE marking).
This Directive applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar gauge including vessels, piping, safety accessories and pressure accessories, Typical examples of pressure equipment and accessories covered include:
• Shell and water tube boilers
• Heat exchangers
• Plant vessels pressurised storage containers
• Industrial pipework
• Safety valves
• Bursting disc safety devices
• Buckling rods
• Controlled safety pressure relief systems
• Pressure switches
• Temperature switches
• Fluid level switches
There are some exclusions listed in the Directive:
• 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) and several other classes of equipment.
Please refer to the machinery directive for detailed requirements
Services that we offer as a notified body
CEM can offer services to approve pressure accessories and safety accessories and can help our clients, including manufacturers, importers and exporters, with conformity assessment services, which are necessary for CE marking the products . These conformity assessment modules what we can provide include:
• Module A1 (internal manufacturing checks with monitoring of the final assessment)
• Module B (EC type-examination)
• Module B1 (EC design-examination)
• Module D (production quality assurance)
• Module D1 (production quality assurance)
• Module E (product quality assurance)
• Module E1 (product quality assurance)
The types of conformity assessment applicable shall be determined by the category of the product as follows;
• I = Module A
• II = Module A1, D1, E1
• III = Modules B1 + D, B + E
• IV = Modules B + D
To help you to select right type of assessment to your product, please contact us for our further assistance.
Directive 2014/68/EU on Pressure Equipment requires the manufacturer to establish the technical documentation. The technical documents must enable the assessment of the conformity of the appliance with the requirements of the Directive. The documentation must contain, wherever applicable, at least the following elements:
• a general description of the pressure equipment
• conceptual design and manufacturing drawings and diagrams of components, sub-assemblies, circuits, etc.,
• descriptions and explanations necessary for an understanding of those drawings and diagrams and the operation of the pressure equipment
• a list of the harmonised standards the references of which have been published in the Official Journal of the European Union, applied in full or in part, and a description of the solutions adopted to meet the essential safety requirements where harmonised standards have not been applied
• results of design calculations made, examinations carried out etc.
• test reports.
The manufacturer or their authorised representative established in the European Union is requested to keep copies of the technical documentation for a period of 10 years after the last product has been placed on the market.
