The German TÜV/ GS approval

Although GS stands for "Geprüfte Sicherheit" (approved safety), you may think of it simply as German Safety. The GS mark indicates that the product was tested and certified for safety according to the "German Equipment Safety Law" by a trustworthy, independent institute. The GS mark is a type-approval mark, followed by periodic factory inspections covering the quality system for the product's production. This law requires us, as the certification body, to frequently check whether the manufacturer is able to maintain all the specifications of the tested product in his mass production. During this factory inspection, we evaluate the implementation of the quality system as relevant for the production, the production environment, and production related testing and measurement equipment.

The equipment corresponds to the requirements of the German Industrial Safety Act and the European low-voltage guidelines. This is certified by the GS-mark of the independent testing institute.
