RAL quality marks have been awarded for particularly high-quality products and services for over 90 years – based on objective criteria and neutrally. As the only awarding authority for quality marks in Germany, RAL defines the requirements for the respective RAL quality mark for each product and service group. RAL involves manufacturers and suppliers, retailers and consumers, testing institutes and authorities. Then RAL publishes the product and service-specific quality criteria and makes them accessible to the public.
All information about the organization of RAL as well as the details of the RAL procedures can be found here.
