ISO 9001
ISO 9001 is the international Standard against which the Quality Management System of a business is evaluated, and is intended to demonstrate that a business can provide a consistent standard of quality in the goods and services it provides to its customers.
Originally introduced to supersede BS 5750 and its adopted Euro Norms in the mid 1980's, the latest revision model of the Standard has now been published, BS EN ISO 9001:2015. This now supersedes all earlier revisions.
