Why Independent Testing Matters
Independent third-party testing and calibration provides objective verification that products and processes meet required standards, satisfies customer and regulatory requirements for impartial evidence of conformity, identifies potential failures before they reach the end user, and supports continuous improvement through accurate measurement and data. UKAS (United Kingdom Accreditation Service) accreditation provides the highest level of assurance that a testing or calibration laboratory operates competently and impartially to BS EN ISO/IEC 17025.
The UK Testing Infrastructure
The UK benefits from one of the strongest testing and metrology infrastructures in the world, underpinned by the National Physical Laboratory (NPL) as the national measurement institute. This feeds through to a network of UKAS-accredited commercial laboratories providing traceable testing and calibration services across all measurement disciplines. Whether you need dimensional, electrical, temperature, pressure, force, or chemical measurement, the UK accredited laboratory network has the capability.
