What is the GS mark?
The GS mark is a seal of approval for "Geprüfte Sicherheit" (Tested
Safety) and it is regulated by German law (German Product Safety
Act). This test mark is recognized worldwide. For you as
manufacturer, the GS mark demonstrates to your customers that you
subjected your product to a voluntary product and safety test
conducted by an officially recognized test center.
What happens to the GS mark if I introduce changes to my product?
Any intended changes to the product must be communicated in advance
to the GS test center in charge. Otherwise, the mark will become
invalid. The test center then assesses whether the product must be
retested and whether this will result in changes in the test report
and the award of the GS mark.
