EN 14015 covers tanks operating at internal pressures up to 500 mbar and vacuum pressures down to 20 mbar. En 14015 Pdf
The scope of EN 14015 includes the following:
EN 14015 is a European Norm (EN) that provides a unified set of requirements for the materials, design, fabrication, erection, testing, and inspection of specific types of steel tanks. The tanks it covers are:
Used on shell welded seams to detect internal flaws. The tanks it covers are: Used on shell
The tank shell must withstand hydrostatic pressure from the liquid inside, as well as wind and seismic loads. EN 14015 utilizes specific calculation methods (like the variable design point method or the one-foot method) to determine the minimum allowable thickness for each shell course (ring). 3.

The standard is under continuous review by CEN/TC 265 (Steel storage tanks). Future revisions are expected to address: non-destructive testing (NDT)

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.
: Includes requirements for welding procedures, non-destructive testing (NDT), and hydrostatic leak testing before the tank is put into service. Where to Access the Document
Designed for atmospheric pressure or low internal pressures, typically ranging from atmospheric up to a maximum overpressure of 60 mbar (6 kPa) and a vacuum underpressure up to 6 mbar (0.6 kPa).
