Standards are revised regularly. EN 14015 has undergone several amendments (e.g., alignment with the Pressure Equipment Directive 2014/68/EU). A "free" PDF from 2012 could be obsolete, leading to a tank that fails a modern legal compliance audit.

“EN 14015 is a competent, Eurocode-based tank standard well suited for above-ground, ambient temperature liquid storage in Europe. It is simpler than API 650 for small-to-mid sized tanks but lacks detailed provisions for seismic, floating roofs, and moderate pressure. For a purely European project without high seismic risk or internal pressure, it’s a solid, enforceable specification.” En 14015 Pdf
API 650 is widely regarded as the global standard for the oil and gas industry, utilizing Imperial units (inches and feet) and focusing heavily on American material grades. EN 14015, conversely, is metric and is harmonized with European material standards (Eurocodes). One significant divergence is the treatment of hydraulic testing. EN 14015 allows for specific alternative testing methods, such as vacuum box testing for tank bottoms, which can offer time savings during construction. Furthermore, EN 14015 is often viewed as providing more explicit guidance on seismic design for specific European ground conditions compared to the broader approaches found in API codes. For companies operating within the European Union or dealing with European engineering firms, compliance with EN 14015 is not just a choice but often a regulatory requirement.
The EN 14015 standard applies to large, site-built storage tanks rather than small, shop-fabricated vessels. To fall under the jurisdiction of this standard, a tank must meet specific physical and environmental criteria. Operating Parameters Standards are revised regularly

A critical aspect of the standard is its focus on serviceability. It does not merely ensure that a tank will not collapse; it ensures that the tank functions correctly during its operational life. This includes strict limitations on shell deformations and settlement. For large-diameter tanks, differential settlement of the foundation can compromise the tank floor or the floating roof mechanism. EN 14015 provides detailed guidance on predicting and mitigating these issues, ensuring the "fitness for service" of the asset over decades of use.
