RAL Quality mark

Background and Meaning

The RAL quality mark 966 - solar energy systems

Not everyone has a sense of quality and a feeling for quality. But everyone wants it.

End customers and consumers, municipal and private clients, companies and corporations – they all rely on test methods and bundled expertise in the form of a RAL quality mark. Manufacturers as well as suppliers and especially the executing companies – they all demonstrate their sense of quality by wearing a RAL quality mark.

The RAL quality mark

Not everyone is allowed to wear it. Only those who have gone through the defined audit process can become a licensed partner of a RAL quality association. Both audits and recertifications are carried out using the general quality and test provisions of the RAL German Institute for Quality Assurance and Labeling.

In the process, the requirements for wearing a RAL quality mark are checked. Finally, the quality association decides on the allocation of the quality mark 966 solar energy systems.

The RAL quality mark 966 solar energy systems stands for the reliability and quality of the labeled products and providers.
