Internal or external floating roofs designed to minimize evaporative product loss and reduce volatile organic compound (VOC) emissions. Inspection, Testing, and Quality Assurance

is the primary European standard governing the structural integrity of vertical steel storage tanks. It supersedes older national standards like DIN 4119 and provides a unified technical framework for liquid storage across the European Union. It focuses strictly on structural design and fabrication , leaving process safety and maintenance to other regulations. 2. Core Technical Specifications

Designers must account for external loads such as wind, snow, and seismic activity to ensure stability.

The standard mandates strict quality controls for chemical composition and mechanical properties of steel plate materials. It defines acceptable grades of carbon-manganese steels and stainless steels to ensure resistance to brittle fracture, especially in low-temperature environments. 2. Bottom Plate Design

When it comes to industrial storage, precision, safety, and compliance are paramount. For engineers, project managers, and constructors involved in building massive storage tanks in Europe, is the foundational standard.

To understand the importance of EN 14015, one must first understand what it governs. The standard is highly specific in its application. It covers vertical, cylindrical tanks constructed from welded steel that are built on-site. These are the iconic silos seen in refineries and petrochemical plants. Crucially, the standard applies to "atmospheric" tanks, meaning tanks designed to withstand internal pressures no greater than 500 mbar (approximately 7.25 psi). This distinguishes its domain from that of high-pressure vessel codes like EN 13445 or ASME Section VIII.

By understanding its scope, key technical requirements, and the process for ensuring compliance, industry professionals can effectively use this standard to manage risk and build for the future. Whether you are an engineer performing calculations, a procurement specialist evaluating a supplier, or a compliance officer verifying regulatory adherence, the EN 14015 standard is an indispensable reference on your desk.

The full text of the standard organizes technical requirements sequentially from raw metallurgy to final on-site commissioning. Material Requirements & Limits

The sets specifications for the materials, design, fabrication, and testing of site-built, vertical, cylindrical, above-ground welded steel tanks for liquids at ambient and elevated temperatures. It serves as a key European standard, often replacing older national codes like DIN 4119 and aligning with Eurocode 3. Key Technical Requirements
