Background: GS certification in German

GS stands for "Gepruefte Sicherheit"tested safety and has been a leading certification scheme since its implementation in 1977. The GS mark is a voluntary mark based on German law, however, it is a well-known safety mark throughout Europe that is used by many as a reliable basis for CE marking. Research continually demonstrates that the GS mark is well respected by consumers and end users in the EU market, with the placing, or not, of a GS Mark on a product often a key factor when making purchasing decisions.
