CPV code 72225000 designates System quality assurance assessment and review services in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
72225000 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 72220000 (Systems and technical consultancy services).
