Tanks for the transport of dangerous goods - Metallic pressure tanks - Design and construction

This document specifies the minimum requirements for the design and construction of metallic pressure tanks having a maximum working pressure exceeding 50 kPa (0,5 bar), for the transport of dangerous goods by road and rail and sea. This document includes requirements for openings, closures and structural equipment; it does not cover requirements of service equipment. For tanks for the transport of cryogenic liquids, EN 13530 1 and EN 13530 2 apply.
Design and construction of pressure tanks according to the Scope of this document are primarily subject to the requirements of RID/ADR, Subsections 6.8.2.1, 6.8.3.1 and 6.8.5, as relevant. In addition, the relevant requirements of RID/ADR, Table A, columns 12 and 13, to Chapters 3.2, 4.3 and Subsection 6.8.2.4 apply. For the structural equipment RID/ADR, Subsections 6.8.2.2 and 6.8.3.2 apply, as relevant. The definitions of RID/ADR, Subsection 1.2.1, are referred to. For portable tanks see also RID/ADR, Chapter 4.2 and Sections 6.7.2 and 6.7.2. In addition, the relevant requirements of RID/ADR, Table A, Columns 10 and 11 to Chapters 3.2, 4.2, and Sections 6.7.2 and 6.7.3 apply. The paragraph numbers above relate to the 2017 issue of RID/ADR which are subject to regular revisions. This can lead to temporary non-compliances with EN 14025.
This document is applicable to liquefied gases including LPG; however for a dedicated LPG standard see EN 12493.
If not otherwise specified, provisions which take up the whole width of the page apply to all kind of tanks. Provisions contained in a single column apply only to:
tanks according to RID/ADR Chapter 6.8 (left-hand column);   portable tanks according to RID/ADR Chapter 6.7 (right-hand column).

Overview

EN 14025:2018/prA1 - Tanks for the transport of dangerous goods - Metallic pressure tanks - Design and construction - is a CEN standard that specifies the minimum requirements for design and construction of metallic pressure tanks intended for the transport of dangerous goods by road, rail and sea. It applies to metallic pressure tanks with a maximum working pressure exceeding 50 kPa (0.5 bar) and covers structural aspects such as openings, closures and structural equipment. Service equipment requirements are excluded. For cryogenic tanks and dedicated LPG rules, the standard points to EN 13530 series and EN 12493 respectively.

Note: prA1 is a draft amendment submitted to CEN members (January 2020) and includes corrections to the scope, a formula (37) and a pressure symbol in Annex A.

Key topics and technical requirements

• Scope: Metallic pressure tanks for transport of dangerous goods (road, rail, sea); portable tanks guidance referenced to RID/ADR chapters.
• Design & construction criteria: Minimum structural requirements, strength calculations and construction rules for tanks with working pressure >50 kPa.
• Openings and closures: Requirements for manholes, valves, fittings and closures to ensure containment during transport.
• Structural equipment: Supports, saddles, mounting and protective structures; provisions differ for tanks under RID/ADR Chapters 6.8 (tanks) and 6.7 (portable tanks).
• Regulatory alignment: Designed primarily in the context of RID/ADR requirements (subsections and table columns referenced in the standard); definitions are aligned with RID/ADR Subsection 1.2.1.
• Corrections in prA1: scope references for portable tanks corrected; Formula (37) corrected; symbol for actual pressure in A.6.4.2 corrected (actual pressure P = 0.04 MPa).

Applications and who uses this standard

• Tank manufacturers and designers: for design validation, material selection and welding/construction requirements of metallic pressure tanks.
• Compliance and certification bodies: for conformity assessment against RID/ADR and national transposition of EN 14025.
• Transport operators and fleet engineers: to verify tanks meet structural integrity and safety requirements for hazardous goods transport.
• Inspection and maintenance organizations: to interpret design limits, openings/closures requirements and structural equipment criteria during inspections.
• Regulators and consultants: for aligning national rules with European ADR/RID provisions referenced by the standard.

Related standards and references

• RID/ADR: Primary regulatory framework referenced throughout (Chapters 3.2, 4.2, 4.3, 6.7, 6.8 and Table A columns).
• EN 13530-1 / EN 13530-2: for tanks transporting cryogenic liquids.
• EN 12493: dedicated LPG tank standard.

This standard is essential for safe, compliant design and construction of metallic pressure tanks used in the transport of dangerous goods and should be used together with the RID/ADR regulatory texts and the related EN standards listed above.
