The German TÜV/GS

The "German TÜV" is a independent institution that assesses products for safety and reliability. When a product passes the strict regulations it is awarded the TÜV/GS mark which indicates that the product was tested and certified for safety according to the "German Equipment Safety Law". The GS mark is a certification that includes periodic factory inspections covering the quality system for the product's production. This law requires inspectors to frequently assess whether the manufacturer is able to maintain all the specifications of the tested product in his production. During this factory inspection, the implementation of the quality system, the production environment, and production related testing and measurement equipment is evaluated.
