✅ Eurocode alignment – Uses EN 1993-1-6 for shell stability, EN 1991-4 for wind/snow loads. Ideal for projects in EU/UK.
✅ Site-built focus – Explicitly covers field erection, unlike shop-welded tank standards.
✅ Clear hydrostatic test procedure – More prescriptive than some older national standards.
✅ Frangible roof joint – Annex C provides a direct method for weak roof-to-shell weld to avoid tank rupture during overpressure.
✅ Material grades – Includes common European steels (S235, S275, S355) with J0, J2, K2 impact grades.
EN standards are typically sold and distributed by national standards bodies and standards organizations; authorized PDFs come from those sources. (Note: I cannot provide copyrighted standard PDFs.)
If a tank fails and causes environmental damage or injury, your legal defense will crumble if you admit to using an unlicensed, non-official copy of the standard. Courts expect you to use the current, authorized version. En 14015 Pdf
| Standard | Region | Key Difference | |----------|--------|----------------| | EN 14015 | Europe / International | Site-built, flat-bottomed, ambient temp, low pressure. | | API 650 | USA / Global | Similar scope but different design rules, inspection, and annexes. | | BS 2654 | UK (withdrawn) | Predecessor to EN 14015. | | EN 1993-4-2 | Eurocode | Part of Eurocode for tanks – complements EN 14015. | | DIN 4119 | Germany | Old German standard – largely replaced. |
EN 14015 is often harmonized with PED 2014/68/EU (Pressure Equipment Directive) when tanks operate above atmospheric pressure. ✅ Eurocode alignment – Uses EN 1993-1-6 for
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.
Finite element analysis (FEA) and tank design software (like TANK or PV Elite) often reference the standard. Users need the PDF for validation and audit trails. EN standards are typically sold and distributed by
EN 14015 addresses the design and construction of the following tank elements:
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.
