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" .
EN 14015 sets out several key requirements for the design, manufacture, and installation of fixed steel tanks. These requirements include:
Organizations like BSI (UK), DIN (Germany), or AFNOR (France). En 14015 Pdf

The standard dictates the use of thicker butt-welded annular plates under the shell wall to distribute heavy vertical loads.
It specifies the grades of carbon and stainless steel that are permissible, ensuring the metal can withstand the hydrostatic pressure of the stored liquid. These requirements include: Organizations like BSI (UK), DIN
EN 14015 utilizes Eurocode-aligned steel grades, which may not always have a direct 1:1 equivalent in the API system. How to Access the Standard
: EN 14015 replaced the older British standard BS 2654 (which was withdrawn in 2006) and is considered an alternative to API 650 (American standard) for European and international projects.
Does not apply to tanks where the product is refrigerated to remain liquid at atmospheric pressure. Pressure Equipment Directive (PED):
❌ – Limited to low internal pressure (≤ 50 mbar). For higher pressure, use EN 13445. ❌ Refrigerated storage – Excludes fully refrigerated LNG/ethylene tanks (use EN 14620). ❌ Seismic – References Eurocode 8 but lacks detailed tank-specific seismic detailing (API 650 Appendix E is more comprehensive). ❌ Aging – Published 2004, no active amendment for newer materials (e.g., thermomechanical steels). ❌ Floating roofs – Only briefly referenced; you’ll need API 650 Appendix H or ISO 28300 for details.
