LPG equipment and accessories - Welded steel tanks for liquefied petroleum gas (LPG) - Road tankers - Design and manufacture

This European Standard specifies minimum requirements for materials, design, construction and workmanship procedures, and tests for welded LPG road tanker tanks and their welded attachments manufactured from carbon, carbon/manganese and micro alloy steels.
There is no upper size limit as this is determined by the gross vehicle weight limitation.
This European Standard does not cover tanks for tank containers.
NOTE 1   In the context of this standard the term "road tanker" is understood to mean “fixed tanks” and “demountable tanks” as defined in ADR.
NOTE 2   The equipment of the tanks and the inspection and testing after assembly is covered by EN 12252, and EN 14334, respectively.
NOTE 3   The design type of the road tanker is subject to the approval by the competent authority, as required by ADR.

Overview

EN 12493:2008/FprA1 (CEN) defines minimum requirements for the design and manufacture of welded steel tanks for liquefied petroleum gas (LPG) road tankers. It covers tanks and welded attachments made from carbon, carbon/manganese and micro‑alloy steels for both fixed and demountable road tankers (as defined by ADR). There is no intrinsic upper tank size limit (size is governed by gross vehicle weight). This standard does not apply to tank containers. The FprA1 amendment updates LPG terminology and adds environmental and testing references.

Key topics and technical requirements

• Materials and metallurgy: permitted steel types (carbon, carbon/manganese, micro‑alloy) and related material testing requirements.
• Design principles: structural design, surge plate guidance (section capacities), manufacturing tolerances and consideration of filling limits under ADR.
• Welding and fabrication: qualified welding procedures, preheat/post‑weld heat treatment guidance and environmental aspects of welding processes.
• Workmanship and manufacturing controls: dimensional tolerances, inspection openings/manholes, welded attachments and assembly procedures.
• Testing and inspection: mandatory tests and non‑destructive testing (NDT) techniques referenced (ultrasonic and magnetic particle testing standards updated in the amendment).
• Marking and documentation: nameplate content (capacity, pressures, material, Pi mark and notified body identification), serial and approval numbers.
• Environmental considerations: lifecycle and production‑stage environmental guidance, recommendation to follow ISO 14000 series and EN 14717 (welding environmental checklist), plus Annex M listing environmental impacts.
• Regulatory interface: design type approval by the competent authority per ADR; references to ADR and applicable EU directives.

Applications and who uses it

• Tank manufacturers and fabricators producing LPG road tanker shells and welded attachments.
• Design engineers and CAD teams responsible for structural and pressure design of LPG road tankers.
• Welding coordinators and NDT inspectors implementing EN ISO procedures for weld qualification and testing.
• Notified bodies, competent authorities and certification organizations performing type approval and marking (Pi mark).
• Fleet operators, vehicle integrators and maintenance organizations ensuring compliance with ADR and safe in‑service performance.
