Accredited Test Centre for Wood Firing Systems FHNW

The testing centre for wood-burning stoves is accredited as a type C laboratory by the Swiss Accreditation Service SAS. A type C laboratory is authorised to develop and validate its own test procedures and have these procedures accredited and can therefore respond much more flexibly to the specific needs of customers.
