It is a recognized mark for electrical products, such as office equipment, household appliances and industrial equipment, and is widely accepted throughout Europe. The TüV Rheinland GS Mark signals to the buyer, customer and consumer that the product, as well as the user manual and production process, has been tested by an authorized institution such as TüV Rheinland and is supported by regular surveillance audits.
