What is ISO 9001?
ISO 9001 is the international standard for a quality management system. It sets out how an organisation should plan its work, control its processes, serve customers and keep improving — so that products and services are delivered right, every time.
It applies to any organisation of any size or sector, and it is the only standard in the ISO 9000 family that a company can be certified to. The standard is moving from the 2015 edition to ISO 9001:2026; certificates to the 2015 edition stay valid during the transition period.
