When reviewing the official document, the layout is broken down into structured sections that guide an engineer through the entire lifecycle of a storage tank project. 1. Material Selection and Properties

| Parameter Category | Core Requirement / Value | Explanation / Condition | | :--- | :--- | :--- | | | Not greater than 60 mbar | Distinguishes EN 14015 from higher-pressure vessel codes (e.g., EN 13445) for low-pressure atmospheric tanks. | | Internal Negative Pressure | Not lower than 6.0 mbar | Ensures tank can withstand partial vacuum from product pump-out or vapor condensation without collapsing. | | Design Metal Temperature | Between –40°C and +300°C | Ensures selected steel maintains adequate toughness (resists brittle fracture at cold temperatures) and strength/creep resistance at high temperatures. | | Maximum Allowable Stress | Does not exceed 260 N/mm² (≈260 MPa) | Simplifies design by limiting stress, essentially capping the yield strength of materials used, making tank designs more conservative and predictable. | | Liquid Level | Not higher than top of cylindrical shell | Standard applies to tanks where the maximum liquid level is contained within the cylindrical sidewalls. |
