Simple Pressure Vessels
The Simple Pressure Vessels Directive or SPVD applies to all welded vessels that are exposed to an internal pressure higher than 0.5 bar and contain air or nitrogen, but are not expected to ignite. In general, these pressure vessels are based on simple designs and are produced in bulk.
SPVD is the 2009/105 / EC Directive that harmonizes the laws and directives of all EU members who wish to establish a single series of technical requirements for all pressure vessel equipment in the EU market.
