The Simple Pressure Vessels Directive (SPVD)- 2014/29/EU is a European directive that applies to certain types of simple pressure vessels which need to be sold within the European Economic Area (EEA).
The SPVD applies to simple pressure vessels manufactured in a series. A ‘simple pressure vessel’ means any welded vessel designed to contain an internal pressure greater than 0.5 barg that is air or nitrogen, and not intended to be fired. The maximum working pressure of the vessel can’t exceed 30 bar and the product of the working pressure (PS) and the capacity of the vessel (V) shall not exceed 10,000 bar/litre.
Depending on the type of equipment – its pressure rating multiplied by volume, or the manufacturing standard used – manufacturers may select a procedure from a range of conformity modules, which include:
- Third-party type examination (EU Type Examination)
- Third-party inspection (Certificate of Adequacy or Verification)
Vessels where PS x V exceeds 50 bar/litre must satisfy the essential safety requirements of the SPVD, set out in Annex I. These must undergo a notified body assessment.
