RAL-QUALITY SEAL
Neutral and continuously monitored

Quality seals identify products and services that are manufactured and offered according to high, precise quality criteria. The requirements for the respective quality seal is determined by RAL for each product and service group in a recognition procedure. Manufacturers and suppliers, retailers and end users, testing institutes and authorities are invited to participate in the process. The product- and performance-specific quality criteria cover all aspects, which are important and meaningful for the use. They are certified by RAL and are accessible to everyone.

Quality labels are awarded by quality associations recognised by RAL to manufacturers and service providers. In an initial examination, these must prove that they meet the respective quality and testing requirements. They are then obliged to monitor the provisions continuously and must have them regularly monitored by a neutral body, also.

Currently, there are over 160 quality seals, which mark many thousands of products or are used by service providers. Only RAL assigns quality seals in Germany.
