EN 14015 is specifically tailored for large, site-built, vertical, cylindrical steel tanks with flat bottoms. Unlike shop-fabricated tanks (e.g., those under standards like EN 12285), EN 14015 addresses the unique challenges of field construction, where welding, non-destructive examination (NDE), and dimensional control must be executed on-site. The standard covers tanks with capacities typically ranging from a few hundred cubic meters to over 100,000 cubic meters.
A close reading of the EN 14015 PDF reveals several critical clauses that differentiate it from older or regional standards like API 650 (American Petroleum Institute). en 14015 pdf
Third, the protocol is rigorously defined. The PDF outlines not only the test pressure (typically 1.25 times the design pressure) but also the settlement monitoring and the permissible leak criteria. Without access to the exact wording in the official PDF, an engineer might incorrectly assume a less stringent test, leading to undetected weld defects.

Second, the standard introduces explicit . The bottom plate, especially near the shell-to-bottom junction, experiences high bending stresses. EN 14015 specifies minimum thicknesses and radial widths for these annular plates based on the tank diameter and product density, a detail often overlooked in less rigorous guidelines.
