Welcome to the Swiss Accreditation Service SAS

The Swiss Accreditation Service SAS examines and accredits the following types of conformity assessment bodies (CABs) on the basis of the relevant international standards:

  • Testing laboratories [SN EN ISO/IEC 17025 / SN EN ISO 15189]
  • Calibration laboratories [SN EN ISO/IEC 17025]
  • Reference material producers [SN EN ISO 17034]
  • Proficiency testing providers [SN EN ISO/IEC 17043]
  • Inspection bodies [SN EN ISO/IEC 17020]
  • Certification bodies for management systems [SN EN ISO/IEC 17021-1]
  • Certification bodies for persons [SN EN ISO/IEC 17024]
  • Certification bodies for products, processes and services  [SN EN ISO/IEC 17065]

By means of accreditation (lat. accredere = to give credence to, believe, put faith in) the competence of a body to execute conformity assessments according to specified requirements is formally acknowledged. The aim of the accreditation is to strengthen the confidence in the competence and services of the CAB.
