Eurofins Product Testing - GS Mark

GS - "Geprüfte Sicherheit"

The GS Mark, introduced in 1977, is one of the leading safety marks. It is based on the "German Equipment Safety Law" (Geräte - und Produktsicherheitsgesetz - GPSG). It indicates that the product was tested and certified for safety by an accredited, independent institute - like Eurofins.

The GS mark is a type-approval mark, connected with periodic factory inspections observing the production quality. To maintain the GS mark, the law demands frequent checks (usually annually or every 2 years, depending upon the certificate) to ensure that the manufacturer is able to maintain all the specifications of the tested product in his mass production. During this factory inspection, Eurofins evaluates the implementation of the quality system, the production environment, and production related testing and measurement equipment.

The GS mark, although not required by law, makes a difference in cases where a product's malfunction leads to an accident for which its manufacturer could be held responsible under Germany's (and the EU's) strict product liability laws. It is also a convincing marketing statement, creating customer confidence and purchasing motivation. Manufacturers often find it convenient and economical to obtain the GS-mark together with the legally required CE Marking.
