EN 14015 is the primary European standard for the design and manufacture of site-built, vertical, cylindrical, flat-bottomed, above-ground, welded steel tanks. It ensures these critical structures—used for storing liquids like crude oil, chemicals, and water—are built for maximum safety and durability. Scope and Application
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 EN 14015 include:

EN 14015 is the primary European standard for the design and manufacture of site-built, vertical, cylindrical, above-ground, welded steel tanks used for storing liquids. It specifically addresses flat-bottomed tanks operating at ambient temperatures or higher, typically used for storing crude oil, petrol, chemicals, and water. Core Technical Scope
The BS EN 14015 standard dictates requirements for materials, fabrication, erection, and testing. Key technical limits include:
Operating Pressure: 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
Tank Geometry: Site-built vertical cylinders with flat bottoms. It covers both open-top and closed-top designs, including those with internal or external floating roofs.
Materials: Primarily carbon and stainless steel (often duplex variants), provided the maximum design strength does not exceed Key Design & Manufacturing Requirements EN 14015 provides a comprehensive technical framework for
The standard ensures structural and fabrication integrity through rigorous guidelines: Detailed Comparison Between API 650, API 620, EN 14015
One of the most common debates in the industry is whether to use EN 14015 or the American standard API 650. While both cover similar ground (welded steel tanks), there are crucial differences.
| Feature | EN 14015 | API 650 (American Petroleum Institute) | | :--- | :--- | :--- | | Geographic Preference | Europe, Middle East, Africa | Americas, Asia-Pacific | | Design Philosophy | Eurocode-based (limit state design) | Working stress method (Allowable Stress Design) | | Wind Loads | Uses Eurocode 1 (EN 1991-1-4) | Uses ASCE 7 | | Seismic Design | Uses Eurocode 8 (EN 1998-4) | Uses API 650 Appendix E (specific to petroleum) | | Material Grades | European (S235, S275, S355) | American (A36, A516 Gr 70) | | Inspection Rules | Prescriptive, detailed clauses | More guidance-based |
Key Takeaway: If you search for an "EN 14015 PDF" but your project is in Texas, you probably need API 650. If your project is in Germany or France, EN 14015 is mandatory for legal compliance under the Pressure Equipment Directive (PED).
Notified bodies and insurance inspectors rely on the exact wording of the standard to approve a tank for service. Having a searchable PDF allows them to find "minimum design metal temperature" (MDMT) clauses instantly.
EN 14015 is a rule-based standard using allowable stress methods, not finite element analysis unless specifically noted. EN 14015 is the primary European standard for
If you manage to locate a legitimate copy of the EN 14015 PDF, you will find a structured document divided into key sections:
EN 14015 — 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" — is a European standard that sets technical requirements for welded steel storage tanks built on site. A PDF of EN 14015 typically contains the full standard text: scope, normative references, terms and definitions, design principles, materials, fabrication, welding, inspection, testing, surface treatment, repair, and documentation.
