Welcome to the Swiss Accreditation Service SAS

The Swiss Accreditation Service examines and accredits conformity assessment bodies (CAB) - i.e. calibration and testing laboratories, inspection and certification bodies as well as reference material producers and proficiency testing providers - according to international standards. By means of accreditation the competence of a body to execute conformity assessments according to specified requirements is formally acknowledged. The Swiss Accreditation Service is an important device to create a transparent and qualified infrastructure for conformity assessment bodies in all branches.

The aim of the accreditation is to strengthen the confidence in the competence and services of the CAB.

The reports and certificates issued under an accreditation and which are also recognized abroad within the framework of international agreements support the confidence in the quality of the correspondent products and services. Herewith, the reports and certificates issued by accredited CAB contribute considerably to the elimination of barriers to trade.
