- Specifications exceeding standard and legal requirements<\/li>\n

- Reliable contractors and clear specifications<\/li>\n<\/ul>\n
Contracting parties benefit from these advantages if they acknowledge the RAL quality mark as a proof of bidder eligibility and compliance with technical specifications in their calls for tender.
\nThe reason is the strict Quality and Testing Regulations products and services must comply with in order to be awarded the RAL quality mark. The Regulations cover all relevant properties, including the manufacturer\u2019s reliability and efficiency and the product\u2019s technical and performance standards.<\/p>\n
The RAL quality mark proves that these requirements are met consistently. If contracting parties base their calls for tender on the Quality and Testing Regulations, they can easily use the RAL quality mark as evidence of bidder eligibility and compliance with specifications. This procedure meets all requirements of procurement law in Germany.<\/p>\n
