The Pressure Equipment Directive
(PED 2014/68/EU)

Good engineering practice under the Pressure Equipment Directive (PED) ensures that pressure equipment is designed, manufactured, and operated safely. Manufacturers are responsible for compliance, which is documented through adequate user instructions and labeling. It is also advisable to include a note confirming compliance in the operating manual or as a separate declaration.

Detailed answer

The conformity assessment procedure according to Category I, Module A requires manufacturers to prepare technical documentation proving that the pressure equipment complies with the applicable safety requirements. This documentation must include, among other things, designs, calculations, and test reports, and must be retained for ten years. In addition, the manufacturer must affix the CE marking and issue the EU declaration of conformity.

Detailed answer

This module is based on internal production control (as in Module A) with additional supervision by a notified body. The manufacturer must prepare and retain technical documentation, affix the CE marking, and issue the EU declaration of conformity. The notified body verifies the final product through random checks or testing procedures to ensure conformity with the directive.

Detailed answer

The conformity assessment procedure under Category III, Module H requires a comprehensive quality assurance system covering both the design and manufacturing of pressure equipment. This system is monitored and regularly audited by a notified body. The manufacturer must ensure compliance with the applicable safety requirements, provide full technical documentation and test reports, and maintain regular records of the quality system. The notified body evaluates the system and conducts periodic surveillance audits to ensure continued compliance.
