  Directive

Simple pressure vessels Directive (2014/29/EU)

  Scope

1. This Directive shall apply to simple pressure vessels (‘vessels’) manufactured in series with the following characteristics:

(a) the vessels are welded, intended to be subjected to an internal gauge pressure greater than 0,5 bar and to contain air or nitrogen, and are not intended to be fired;

(b) the parts and assemblies contributing to the strength of the vessel under pressure are made either of non-alloy quality steel or of non-alloy aluminium or non-age hardening aluminium alloys;

(c) the vessel is made of either of the following elements:

(i) a cylindrical part of circular cross-section closed by outwardly dished and/or flat ends which revolve around the same axis as the cylindrical part;

(ii) two dished ends revolving around the same axis;

(d) the maximum working pressure of the vessel does not exceed 30 bar and the product of that pressure and the capacity of the vessel (PS × V) does not exceed 10 000 bar.L;

(e) the minimum working temperature is no lower than – 50 °C and the maximum working temperature is not higher than 300 °C for steel and 100 °C for aluminium or aluminium alloy vessels.

2. This Directive shall not apply to:

(a) vessels specifically designed for nuclear use, failure of which may cause an emission of radioactivity;

(b) vessels specifically intended for installation in or the propulsion of ships and aircraft;

(c) fire extinguishers.

  Description

The Simple Pressure Vessels Directive (SPVD) 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 intende 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 multipled by 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)

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.
