Tests

SATS member laboratories carry out type tests and development tests

  • Tests are carried out in accordance with international and regional standards such as for example IEC, ANSI/IEEE and CENELEC, as well as national standards and client's requirements.
  • When testing according to international standards for certification purposes, all relevant STL Guides and procedures are strictly adhered to.
  • All tests are witnessed by inspectors assigned by SATS Certification and the test reports are counter-signed by the inspector in charge.
