A practical example is the replacement of a leaking sulphuric acid tank at . The order involved the design, manufacture, and supply of a 24m³ capacity tank, which was explicitly built to EN 14015 and Vlarem II (the Flemish environmental regulation). The project highlights several key benefits of specifying EN 14015 compliance:
design and manufacture of site-built, vertical, cylindrical, flat-bottomed, above-ground, welded steel tanks used for storing liquids at ambient temperatures or higher. iTeh Standards Key Specifications of EN 14015
❌ – 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.

The full text of the standard organizes technical requirements sequentially from raw metallurgy to final on-site commissioning. Material Requirements & Limits
The standard focuses solely on the of the basic tank. It explicitly does not provide requirements for process design, operational issues, safety and firefighting facilities, in-service inspection, maintenance, or repair, which are expected to be covered by other codes and practices. The limits of the standard's application are also clearly defined, ending at the face of the first flange in a bolted connection, the first threaded joint, or the first circumferential joint in a pipe, whichever comes first. A practical example is the replacement of a
The EN 14015 standard covers specific industrial applications. It explicitly dictates structural parameters for tanks constructed directly on their operational site rather than fully pre-assembled in a workshop.
Cannot be lower than 20 mbar (2 kPa).
The standard ensures structural integrity and safety for atmospheric storage tanks in the industrial, energy, and chemical sectors.
