Intertek exclusively provides the S Mark. Products bearing this Mark demonstrate compliance with legal European electrical safety requirements via third-party testing

Electrical products sold throughout the EU must bear the CE marking. However, as CE marking is self-declared, impartial testing is not required. Products bearing the S Mark (a voluntary certification) show that Intertek has independently tested and certified that the products fulfill valid safety requirements. With the S Mark, your product may be sold throughout the EU without further safety testing or certification. The testing and certification regimen for the S Mark is the basis for CE marking and the required documentation.

When the safety of electrical and electronic products is certified, the products are tested for the following risks, as specified in the European safety standards: Fire, electric shock, mechanical injuries, radiation injuries and burns and certain types of environmental damage. As a European safety mark, the S Mark communicates to over 450 million people that your products are safe. In Europe, "Safety" begins with S, no matter where you are: Sicherheit (German), Seguridad (Spanish), Sécurité (French), Sicurezza (Italian), Segurança (Portuguese), Säkerhet (Swedish).
