EN 14015 is a harmonized European standard titled "Specification for the design and manufacture of site built, vertical, cylindrical, flat-bottomed, above ground, welded, steel tanks for the storage of liquids at ambient temperature and above" .
This independent oversight provides assurance to owners, insurers, and regulators that the tank is safe and fit for its intended purpose.

) specifically adds requirements for self-supporting aluminium dome roofs. Foundations
These other critical aspects are typically covered by other codes and industry best practices.

A typical third-party inspection service for EN 14015 compliance includes: : National members of CEN (such as AFNOR
Generally less than 500 mbar internal pressure and no lower than 20 mbar internal negative pressure. Some specific iterations limit design pressure to 60 mbar. Temperature Range: Metal temperatures between -40∘Cnegative 40 raised to the composed with power C +300∘Cpositive 300 raised to the composed with power C
The UK version is titled BS EN 14015 and is widely used internationally. DIN Media: For the German version ( DIN EN 14015 ).
Unlike API, EN 14015 uses partial safety factors. Look for "γM" (material factor) and "γF" (load factor). These directly affect your design margin.
: Specifies plate arrangements, joint types, and stiffening rings (e.g., wind girders). 2. Design of Tank Components
The standard specifies requirements for everything from material selection to final inspection. It is applicable to both open-top and closed-top tanks, including those with internal floating roofs. Key design limits under include:
By understanding its scope, key technical requirements, and the process for ensuring compliance, industry professionals can effectively use this standard to manage risk and build for the future. Whether you are an engineer performing calculations, a procurement specialist evaluating a supplier, or a compliance officer verifying regulatory adherence, the EN 14015 standard is an indispensable reference on your desk.
The standard outlines strict requirements for the chemical composition, mechanical properties, and impact toughness of the steel plates used. Because these tanks are built outdoors and subject to varying climates, selecting steel that resists brittle fracture at low ambient temperatures is paramount. Materials typically must comply with EN 10025 or EN 10028 series specifications. 2. Design of Tank Components
