Professional technical assessors from all areas of industry, government, academia, and research are invited to be as third-party position for accreditation of testing laboratories to ensure the technical competence of the laboratories meet specific requirements. Testing laboratories accredited by TAF may use the TAF accreditation symbol on the issued test reports or certificates. The names and data of TAF-accredited testing laboratories are officially posted on the TAF website and constantly updated to provide the correct information to external users in time..
