CE Certification Processes for Pressure Equipment

CE Certification for Pressure Equipment: Process and Requirements Under Directive 2014/68/EU

The European Union’s 2014/68/EU Pressure Equipment Directive (PED) was established to ensure the safe placing of equipment with a certain internal pressure on the market. This directive obligates manufacturers to make their products comply with basic safety requirements and demonstrate this compliance through CE marking.

Products Covered by the Pressure Equipment Directive

Directive 2014/68/EU covers equipment containing gas or liquid that exceeds a certain pressure level. Key products under this scope include:

• Pressure vessels
• Steam boilers
• Piping systems
• Safety accessories (valves, pressure relief valves, etc.)
• Industrial gas cylinders
• Hydraulic and pneumatic systems

Products are categorized based on operating pressure, internal volume, and the hazard classification of the fluid. These categories determine the applicable conformity assessment module and the requirements of the process.

CE Certification Process Under Directive 2014/68/EU

The CE marking process for pressure equipment varies depending on the risk level of the product. The general process includes the following steps:

1. Category Determination
   The equipment is classified from Category I to IV based on operating pressure, internal volume, and the hazard level of the fluid used.
2. Selection of Conformity Assessment Module
   The main conformity assessment modules under 2014/68/EU are:
   • Module A: Based on the manufacturer’s declaration for low-risk products.
   • Module B: Type examination by a Notified Body.
   • Modules C1 – C2: Manufacturing control processes used in conjunction with Module B.
   • Modules D – E: Production and product quality assurance systems.
   • Modules F – G: Testing and verification processes based on batches or products.
   • Modules H – H1: Full quality assurance and design review.
3. Technical Documentation and Testing
   A technical file is prepared to prove that the product meets safety requirements. Pressure tests, material analysis, and performance checks are conducted at this stage.
4. Involvement of a Notified Body
   The involvement of a Notified Body is required for Category II, III, and IV equipment.
5. Addition of the CE Mark
   Once all processes are completed, the manufacturer affixes the CE mark to the product and issues the EU Declaration of Conformity.

Can Pressure Equipment Be Sold Without a CE Certificate?

Pressure equipment under 2014/68/EU cannot be placed on the market in European Union countries or Turkey without the CE mark. Products without the CE mark can be banned from sale if detected during market surveillance and inspections and may be subject to administrative penalties.

Therefore, manufacturers are required to ensure their products comply with legal requirements and market them with the CE mark.
