For evaluating the sound quality of household appliances we created our own mark and defined corresponding criteria. The subjective sound perception and objective values are both considered for the rating. 
Our mark "Usability tested" (fitness for use tested) is awarded to products scoring a "very good" or "good" in the fitness-for-use test and furthermore, meeting all product safety requirements. The tests are performed according to product-specific SLG test plans.
The GS mark documents the compliance of a product with requirements of the German Product Safety Act (ProdSG). Besides a passed type test, a positive factory inspection is also mandatory for a GS certification.
This mark can be used by companies whose QM system meets the requirements of the internationally acknowledged standard DIN EN ISO 9001. The certification is based on audits and document checks and involves an annual surveillance. The mark may be used for advertising but not in connection with products
DIN EN ISO 13485 applies for the medical devices sector. Our mark shows the conformity of your QM system with this standard. It may be used for advertising but not in connection with products.
