The South German cTUVs certification is the North American certification mark of the German company TUV South Germany. As long as it is recognized by OSHA (Occupational Safety and Health Administration) as a testing and certification body of NRTL (National Recognized Testing Laboratory), it can provide testing and certification services for products entering the US and Canadian markets. Having the same qualifications as other NRTL agencies (such as UL, CSA) can help products successfully enter the US and Canadian markets. All NRTL markings (cTUVus, UL, CSA, ETL, cNEMKOus) are equivalent.
DNT, as an authorized laboratory of the German Rhine Institution, can provide cTUVus certification for products according to customer needs and issue testing reports.
