Simple Pressure Vessels Directive
87/404/EEC
What is the Simple Pressure Vessels Directive?
The Simple Pressure Vessels Directive (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)
