TÜVs (German pronunciation: short for German: Technischer Überwachungs-Verein, English: Technical Inspection Association) are German organizations that work to validate the safety of products of all kinds to protect humans and the environment against hazards. As independent consultants, they examine plants, motor vehicles, energy installations, amusement rides, devices and products (e.g. consumer goods) which require monitoring. The many subsidiaries of the TÜVs can also act as project developers for energy and traffic concepts, as problem solvers in environmental protection, and as certification bodies. Many of the TÜV organizations also provide certification for various international standards, such as ISO9001:2008 (quality management system) and ISO/TS16949 (automotive quality management system).
