What is GS?

The Geprüfte Sicherheit ("Tested Safety") or GS mark is a voluntary certification mark for technical equipment. It indicates that the equipment meets German and, if available, European safety requirements for such devices.

Many products, including home appliance products, lamps and lanterns, audio video products, communication products, office equipment, electric tools, electronic toys, electronic measuring instrument and so on need to meet GS requirements; otherwise, it’s difficult to be sold in German.
