These Regulations implement a certain EU directive on the harmonisation of the laws of the member States relating to the making available on the market of simple pressure vessels. The directive provides the technical requirements that ensure the safety of simple pressure vessels through accreditation and market surveillance relating to the marketing of products. The Original EU directive was denoted as the Simple Pressure Vessels (SPV) Directive (2009/105/EC), which was later transposed and aligned with the New Legislative Framework (NLF) of the EU Decision 768/2008/EC and EU Regulation 765/2008/EC.
