PED Compliance and Certification for Pressure Equipment | PRVÁ ZVÁRAČSKÁ, a. s.

Introduction

Pressure equipment plays a critical role in industrial operations where high pressure and temperature conditions are involved. Any failure in such systems can lead to severe safety hazards, environmental impact, and financial loss. To control these risks, the European Union enforces strict regulatory requirements through the Pressure Equipment Directive (PED) 2014/68/EU.

PED Certification ensures that pressure equipment meets these mandatory safety, design, and manufacturing requirements before being introduced into the European market. PRVÁ ZVÁRAČSKÁ, a. s. performs conformity assessment activities required for PED Certification.

What PED Certification Represents

PED Certification is a formal confirmation that pressure equipment complies with the essential safety requirements defined in Directive 2014/68/EU. It applies to equipment operating above 0.5 bar and ensures conformity before CE marking.

Applicable Equipment under PED Certification

PED Certification applies to a broad category of pressure-related components:

• Pressure vessels
• Steam and hot water boilers
• Metallic and non-metallic piping systems
• Heat exchangers
• Pressure safety devices
• Assemblies of pressure equipment

Expanded Scope of PED Certification

PED Certification is relevant across both traditional and emerging industries, including:

• Oil and gas processing
• Power generation plants
• Chemical manufacturing
• Food and beverage production
• Pharmaceutical facilities
• Hydrogen systems and renewable energy installations
• LNG and cryogenic applications

This wide applicability highlights the importance of PED Certification in modern industrial systems.

Equipment Classification in PED Certification

PED Certification requires classification of equipment based on risk parameters such as pressure, volume, and fluid characteristics.

Classification Levels:

• SEP (Sound Engineering Practice): Minimal regulatory involvement
• Category I: Low-risk equipment
• Category II: Intermediate risk
• Category III: High-risk applications
• Category IV: Critical systems with maximum oversight

Higher categories in PED Certification require more rigorous conformity assessment and involvement of PRVÁ ZVÁRAČSKÁ, a. s..
