PED 2014/68/EU Certification for Pressure Equipment Compliance | PRVÁ ZVÁRAČSKÁ, a. s.

The Pressure Equipment Directive 2014/68/EU (PED) establishes essential safety requirements for pressure equipment intended for the European market. It ensures that equipment used in industrial applications meets strict regulatory and safety standards.

For manufacturers, PED certification is a mandatory requirement for CE marking and market acceptance within the European Economic Area (EEA).

Scope of PED 2014/68/EU

The directive applies to pressure equipment operating above 0.5 bar pressure. It covers critical components and systems such as:

• Pressure vessels
• Boilers
• Industrial piping systems
• Heat exchangers
• Safety accessories

All applicable equipment must comply with defined safety and technical requirements before being placed on the market.

Equipment Classification Under PED

PED categorizes equipment based on risk levels:

• Category I – Low risk
• Category II – Medium risk
• Category III – High risk
• Category IV – Highest risk

Classification depends on:

• Maximum allowable pressure (PS)
• Volume (V)
• Fluid type (hazardous or non-hazardous)

Higher categories require stricter conformity assessment procedures.

Conformity Assessment Requirements

Compliance with PED involves a structured evaluation process covering:

• Design verification
• Material traceability
• Manufacturing control
• Inspection and testing
• Final certification

The extent of assessment depends on the equipment category and associated risk level.

Welding and Quality Requirements

Welding is a key aspect of pressure equipment manufacturing under PED certification. Requirements include:

• Qualification of welding procedures
• Certification of welders and operators
• Monitoring of fabrication processes
• Non-destructive testing (NDT)

These measures ensure structural integrity and operational safety.

Role of Notified Body

A Notified Body is an independent organization designated by the European Union for conformity assessment.

PRVÁ ZVÁRAČSKÁ, a. s., as Notified Body 2408, is authorized to perform:

• Design examination
• Evaluation of technical documentation
• Quality system assessment
• Inspection during manufacturing
• Verification and certification for CE marking

The level of involvement is determined by the equipment category and selected conformity assessment procedure.

PED Certification Process

The certification process typically includes the following stages:

1. Classification

Identification of equipment category based on technical parameters.

2. Design Evaluation

Assessment of engineering design and calculations.

3. Material Verification

Review of material certificates and compliance with standards.

4. Manufacturing Control

Implementation of controlled production and welding processes.

5. Inspection and Testing

Execution of NDT, pressure testing, and final inspection.

6. Certification

Approval for CE marking after successful conformity assessment.

Importance of PED Certification

PED certification ensures:

• Compliance with European regulations
• Authorization for CE marking
• Safety and reliability of pressure equipment
• Consistency in manufacturing and inspection
• Acceptance in the European market

It establishes a standardized framework for pressure equipment across industries.

Key Compliance Considerations

Manufacturers must ensure:

• Accurate classification of equipment
• Complete technical documentation
• Qualified welding procedures and personnel
• Controlled manufacturing processes
• Proper inspection and testing records

These elements are essential for successful certification.

Conclusion

2014/68/EU PED certification is a critical requirement for pressure equipment entering the European market. It defines a structured approach to safety, design, manufacturing, and verification.

Compliance with the directive ensures that equipment meets European standards and qualifies for CE marking. PRVÁ ZVÁRAČSKÁ, a. s., as Notified Body 2408, performs conformity assessment activities required for certification.
