The Swiss Accreditation Service (SAS) or "Schweizerische Akkreditierungsstelle" is Switzerland’s national accreditation body, responsible for accrediting organizations involved in testing, calibration, certification, and inspection services. Established in 1991, SAS operates under the State Secretariat for Economic Affairs (SECO). Its primary role is to ensure that conformity assessment bodies in Switzerland meet rigorous international standards of competence and reliability, thereby supporting the quality, safety, and efficiency of products and services across various industries.

SAS collaborates with a range of national and international organizations to maintain high standards of accreditation. It is a full member of the International Laboratory Accreditation Cooperation (ILAC) and the International Accreditation Forum (IAF). Through these memberships, SAS participates in mutual recognition arrangements that facilitate the global acceptance of test and calibration results, certifications, and inspection reports issued by accredited Swiss bodies. These international partnerships help reduce technical barriers to trade and enhance the global competitiveness of Swiss products and services.

To maintain its leadership in accreditation, SAS continuously updates its accreditation criteria and processes to align with international best practices. It provides essential services including the accreditation of laboratories, certification bodies, and inspection agencies. By ensuring the quality and reliability of these services, SAS supports regulatory compliance, consumer protection, and industrial innovation.
