PED Pressure Equipment Directive (PED 2014/68/EU) Certification Services

The Pressure Equipment Directive (2014/68/EU PED) is a European Union regulation that defines the essential safety requirements for the design, manufacture, and placing on the market of pressure equipment operating under pressure. Within the scope of applicable regulations in Türkiye, conformity assessment and certification processes are applied for products falling within certain categories.

Our accredited organization supports manufacturers in accessing both national and international markets through conformity assessment activities carried out under PED 2014/68/EU.

What is the PED Pressure Equipment Directive?

The Pressure Equipment Directive is a technical regulation that defines the safety requirements for equipment with a maximum allowable pressure greater than 0.5 bar. The directive aims to protect human health, reduce environmental risks, and ensure the safe use of products.

The procedures applied for products covered by PED vary depending on the product category and its associated risk level.

Products Covered Under PED 2014/68/EU

The main products covered by the Pressure Equipment Directive include:

Pressure Vessels

Tanks, air receivers, expansion vessels, and similar equipment used for storing gases or liquids under pressure.

Piping Systems

Pressurized pipelines and connection systems used in industrial facilities.

Steam Boilers

Hot water boilers, steam generators, and equipment used in power generation systems.

Safety Accessories

Safety valves, pressure limiting devices, and protective equipment.

Pressure Accessories

Filters, manifolds, connection elements, and auxiliary system components.

Why is CE Marking Important for Pressure Equipment?

The CE mark is a conformity marking indicating that the product has been assessed in accordance with relevant European Union legislation. For pressure equipment, CE marking:

• Indicates that the product meets technical requirements,

• Ensures free circulation in the European market,

• Demonstrates compliance with safety criteria,

• Shows that the manufacturer has fulfilled its legal obligations.

Depending on the product category, notified and accredited bodies may be involved in the conformity assessment process.

Pressure Equipment Categories

Under PED 2014/68/EU, products are classified as:

• SEP (Sound Engineering Practice),

• Category I,

• Category II,

• Category III,

• Category IV

The appropriate category is determined based on operating pressure, volume, fluid type, and technical characteristics.

PED Modules – Conformity Assessment Modules for Pressure Equipment

Various conformity assessment modules are applied under the directive, including:

Module A – Internal Production Control

A procedure carried out under the manufacturer’s sole responsibility.

Module B – EU Type Examination

Covers the examination of product design.

Module C2 – Conformity to Type Based on Internal Production Control Plus Supervised Product Checks at Random Intervals

Includes post-production verification activities.

Module D – Production Quality Assurance

Covers evaluation of the production process through a quality system.

Module E – Product Quality Assurance

Involves assessment of the quality system related to final product inspection.

Module F – Product Verification

Covers verification activities performed on each product or batch.

Module G – Unit Verification

A conformity assessment applied to a single product unit.

Modules H and H1 – Full Quality Assurance

Includes comprehensive assessment of design, production, and quality processes.

Standards Used for Pressure Equipment

The commonly used standards in certification processes include:

EN 13445

Standard for unfired pressure vessels.

EN 13480

Standard for industrial metallic piping systems.

EN ISO 3834

Defines quality requirements for welding processes.

EN 10204

Covers material certificates and inspection documents.

EN ISO 9606

Defines qualification requirements for welders.

These standards are important references for product safety and technical compliance.

Certification Process Under the Pressure Equipment Directive

The certification activities generally consist of the following stages:

1. Application submission,

2. Review of technical documentation,

3. Required inspection and verification activities,

4. Completion of conformity assessment,

5. Issuance of certification if all requirements are met.

The procedures and requirements may vary depending on the product group.
