2014/68/EU Pressure Equipment Directive

2014/68/EU Pressure Equipment Directive is a regulation implemented to facilitate the free movement of pressure equipment within the European Union, establish necessary safety regulations for the protection of human health and the environment, and it is applicable both in Turkey and European Union member countries, requiring products to bear the CE marking.

The 2014/68/EU PED Directive defines minimum requirements for the design, manufacture, assembly, and use of pressure equipment to ensure human health and safety, as well as environmental protection. These requirements are inspected and certified by relevant Notified Bodies before the equipment is certified and placed on the market.

As a certification service provider, we assist manufacturers throughout all stages of establishing the quality system, obtaining welder certification, obtaining welding procedure approvals, and successfully completing the certification process.

The Pressure Equipment Directive provides manufacturers with options for conducting conformity assessments. Based on information such as the intended use of the product, pressure, volume, and the fluid to be used, products are classified, and their category in the directive is determined. Manufacturers seeking to affix the CE marking to their products can choose one of four different categories as specified in the directive, depending on the risk class of their products. The most commonly selected modules by manufacturers are as follows:

  • Module A: Internal Audit
  • Module B: Type Examination
  • Module C1: Conformity to Type Based on Serial Production
  • Module C2: Production Control
  • Module D: Product Quality Assurance
  • Module E: Quality Assurance of the Production Process
  • Module F: Final Product Quality Assurance
  • Module G: Unit Verification
  • Module H: Conformity to Type Based on Quality Assurance
  • Module H1: Conformity to Type Based on Full Quality Assurance

Which equipment groups are covered by Pressure Equipment Directives?

Pressure equipment refers to mechanical or electronic devices commonly used to store, transport, or process liquids, gases, or vapors under pressure. These equipment serve various purposes and find extensive use in many industrial processes and applications. Here are some examples of pressure equipment:


Compressors are machines used to compress gases and produce high-pressure air or gas. They are commonly used in applications such as air conditioning systems, industrial processes, and energy production.



Boilers are vessels used to heat water and generate steam under pressure. They are widely employed in energy production and heating processes, such as steam turbines or heating systems.


Pressure Vessels

Pressure vessels are containers designed to store or transport liquids or gases under pressure. They come in various sizes and are designed for different purposes.


Tubes and Pipes

Tubes and pipes are used to transport pressurized gases or liquids. They are essential for conveying industrial gases, water, oils, and other fluids.


Pressure Filters

Pressure filters are employed in chemical processes and industrial applications to separate solid particles or other impurities from fluids.


Hydraulic Systems

Hydraulic systems use pressurized fluids to generate mechanical power. They are commonly used in applications like construction equipment, cranes, and automobiles.


Pump Systems

Pump systems are used to transport liquids under high pressure or to create fluid flow. They are employed in various applications, including irrigation, chemical industries, and water supply.


Pressure Tanks

Pressure tanks are used for storing or transporting pressurized fluids. They find applications in water storage tanks and fuel storage tanks, among others.


Fire Suppression Equipment

Pressure-based fire suppression equipment, such as fire extinguishers and sprinkler systems, are used to control or extinguish fires.


Air Tanks

Air tanks store pressurized air, often produced by air compressors, for use in industrial tools, vehicles, and manufacturing processes.


Pressure equipment is an essential part of various industries and plays a crucial role in ensuring safe and efficient processes. However, the design, manufacturing, maintenance, and use of pressure equipment must adhere to safety standards and regulations, as improper handling can pose significant risks. As a result, pressure equipment is typically subject to specific regulations and safety standards to ensure its safe operation.
