Accreditation System for Conformity Assessment Bodies (CABs)


Conformity Assessment Bodies (Testing/Calibration Laboratories, Reference Materials Producer, and Product Certification Bodies, referring “CABs” hereinafter) Accreditation System is a scheme in which an authoritative accreditation body approves CABs that conform to relevant requirements for their competence to conduct test calibration, or other conformity assessment activities in specific technical areas. The aim is to assure the confidence and reliability of the data measured, tested, and calibrated by laboratories or the results of product certification. In the most countries in Europe and USA purchasers (users) require suppliers (manufacturers) to attach the test data to products and a lot of suppliers use the data tested by the third-party laboratories independent from relevant parties. In these cases, test reports issued by accredited testing laboratories are value-adding and useful for purchasers and suppliers to effective trade.

Accreditation Body and CABs

The accreditation body is an organization to evaluate the conformity and competence of CABs against international standards and guides or other requirements under the accreditation system. To ensure the international harmonization, the accreditation body itself is required to conform to relevant international standards.
