About us

The Global Accreditation System (GAS) was established to assess the competence and impartiality of certification bodies, inspection bodies, laboratories, and other organizations performing conformity assessment activities.
The main objective of GAS is to ensure trust in the results of these organizations by conducting an objective, transparent, and professional accreditation process that complies with international principles.
The activities of GAS are aimed at improving the quality and reliability of conformity assessment services, fostering international cooperation, mutual recognition of accreditations, and ensuring open access to information about accredited bodies.
The organization operates based on independence, impartiality, transparency of processes, and equal treatment of all applicants.
