Simple Pressure Vessels (SPV) Directive 2009/105/EC

What is the Simple Pressure Vessels (SPV) Directive?

The SPV applies to you if you design or manufacture certain types of simple pressure vessels which are placed on the market within the European Economic Area.

What does the directive cover?

The SPV applies to simple pressure vessels manufactured in series. A 'simple pressure vessel' means any welded vessel subjected to an internal pressure greater than 0,5 barg which is intended to contain air or nitrogen and which is not intended to be fired.

The simple pressure vessel must have pressure parts made from either non-alloy quality steel or non-alloy aluminium or non-age hardening aluminium alloys. The maximum working pressure of the vessel must not exceed 30 bar and the product of the maximum working pressure (PS) and the capacity of the vessel (V) shall not exceed 10 000 bar/litre.

Vessels where PS x V exceeds 50 bar/litre must satisfy the essential safety requirements set out in Annex I of the Directive and undergo a notified body assessment.

Depending upon the type of equipment - its pressure rating x volume or the manufacturing standard used - manufacturers may select a procedure from a range of conformity modules, which include:

  • manufacturers self-certification;
  • third-party type examination (EC Type Examination);
  • third-party inspection (EC Certificate of Adequacy or EC Verification).
