It is a quality infrastructure established in order to support the reliability and validity of the works carried out by the credit conformity assessment bodies and therefore the conformity confirmation documents (test and inspection reports, calibration certificates, management system documents, product documents, personnel documents, etc.)

The accreditation of conformity assessment bodies is carried out on the basis of the international standards that determine the qualification criteria for the relevant conformity assessment bodies, the relevant sector-specific requirements and the requirements specified in the guidebooks determined by the regional or international accreditation bodies, which are accepted worldwide.

A product or service with a conformity certificate issued by an accredited conformity assessment body inspires confidence that it meets the requirements applicable to that product or service. Thanks to this systematic, accreditation contributes to the removal of technical barriers in trade.

At the point of global acceptance of accredited services, questions arise about the reliability of the accreditation service itself.

The trust mechanism between accreditation organizations is established by the multilateral recognition agreements made with international or regional organizations such as IAF (International Accreditation Forum), ILAC (International Laborataur Accreditation Association), EA (European Accreditation Association) etc.
