Accredited Test labs

The Accredited KNX Test Labs are those Test Laboratories that are authorized to carry out the software testing of a KNX device. These are neutral Test Laboratories that work independently from the manufacturers, therefore any manufacturer of KNX devices can have his products tested. 

Only few tests are still carried out by KNX Association by means of product audits and not by these third parties, i.e. :

  • Tests for system features, for which no approved Test Specification exists (yet).
  • Approved Test Specifications, for which no test lab has submitted a request for accreditation at KNX (yet).
