The GS Certification system was established in 1968, initially under the Equipment Safety Act (GSG). After multiple revisions, the current legal basis is the GPSG (Product Safety Act) updated in 2015. The GS mark applies only to products that have passed Type Testing and Factory Inspection Qualified products, indicating that the product has exceeded the minimum regulatory requirements for safety and has met higher safety standards.
GS Certification mainly targets electrically operated products (handheld, portable, fixed, mobile), including household appliances, IT and communication equipment, lighting products, power tools, laboratory equipment, and measurement/control equipment. In recent years, the scope has been expanding, with some non-electricalproducts (such as bicycles, furniture, etc.) can also obtain the GS mark through specific safety standards.
Unlike the CE mark, GS Certification is voluntary and must be assessed by an authorized Certification Body (such as TUV, VDE, SGS, etc.). GS Certification requires more stringent Safety Tests and periodic Factory Inspection. The Certification Cycle is longer and costs are higher, but its market recognition and added value are also higher. The GS mark is valid for up to 5 years, during which annual follow-up inspections are required.
GS is the abbreviation for the German "Geprufte Sicherheit", meaning
"tested safety." Although the GS mark is voluntary, its high recognition in the German and European markets has made it an important qualification for manufacturers entering the premium European market.
