The Evaluation Guideline covers the production of:
- Single and double walled underground horizontal cylindrical steel tanks with a maximum volume of 150 m³ for atmospheric storage of liquids (scope 1A);
- Single and double walled aboveground horizontal cylindrical steel tanks with a maximum volume of 150 m³ for atmospheric storage of liquids (scope 1B);
- Single and double walled aboveground vertical cylindrical steel tanks with a maximum volume of 5 m³ for atmospheric storage of liquids (scope 1C);
- Single and double walled aboveground non-cylindrical steel tanks with a maximum volume of 3 m³ for atmospheric storage of liquids (scope 1D);
- Spill containers under aboveground tanks or barrels (scope 2A);
- Spill containers for collecting the spillage of liquids during connecting and disconnection of filling or drain hoses (scope 2B).
A tank can be single or double walled. Single walled tanks must be placed in a spill container. Horizontal cylindrical tanks may be divided into compartments. The Evaluation Guideline indicates when tanks comply with EN 12285. Spill containers can also made of aluminium.
For whom?
BRL-K21051/01 is intended for suppliers/producers of tanks and spill containers.
When is it necessary?
Supplying/producing of tanks and spill containers under the product certificate BRL-K21051 give users, but also the competent authority, the confidence that the tanks and/or spill containers are produced under a quality assurance system audited by Kiwa.
A tank or spill container, except spill containers (scope 2B), will be supplied with a declaration of conformity. This declaration of conformity in combination with a tank installation certificate in accordance with BRL SIKB 7800 give confidence that it is a safe and reliable tank installation. The combination of declaration of conformity and tank installation certificate in accordance with BRL SIKB 7800 is also the evidence that the tank installation is in accordance with local laws and regulations (NL).
The outside of tanks and spill containers shall be provided with a corrosion protection system. For this purpose, a durable paint system, based on the corrosion class at the installation site, must be applied in accordance with BRL-K790. As an option, the inside of a tank can be provided with an internal coating. This internal coating must be applied in accordance with BRL-K790.
