Every RAL Gütezeichen (Quality Mark) is approved and awarded in a binding process according to the same fundamental guidelines. This RAL quality assurance system covers areas such as defining the scope of validity through to the approval process, as well as awarding and monitoring the quality mark through to its possible withdrawal. This system is responsible for ensuring that RAL Gütezeichen (Quality Marks) are neutral and particularly reliable. It differentiates RAL Gütezeichen (Quality Marks) from all other labelling systems.
