Tanks for the transport of dangerous goods - Metallic gravity-discharge tanks - Design and construction
This document specifies requirements for the design and construction of metallic gravity-discharge tanks intended for the carriage of substances having a vapour pressure not exceeding 110 kPa (1,1 bar) (absolute pressure) at 50 °C.
NOTE 1 Gravity-discharge tanks have no maximum working pressure. However, during operation, pressure in the shell may occur, for example due to flow restrictions in vapour recovery systems or opening pressures of breather devices. It is important that these operating pressures do not exceed the test pressure of the tank or 0,5 bar, whichever is the highest.
This document specifies requirements for openings, closures, pipework, mountings for service equipment and structural equipment.
NOTE 2 This document does not specify requirements for items of service equipment other than pipes passing through the shell.
This document is applicable to aircraft refuelers that are used on public roads. It is also applicable to inter-modal tanks (e.g. tank containers and tank swap bodies) for the transport of dangerous goods by road and rail.
NOTE 3 This document is not applicable to fixed rail tank wagons.

Overview
EN 13094:2020/prA1 is a CEN standard specifying requirements for the design and construction of metallic gravity-discharge tanks used for the transport of dangerous goods. It applies to tanks intended to carry substances with a vapour pressure not exceeding 110 kPa (1.1 bar) absolute at 50 °C. The standard covers shell design, openings, closures, pipework, mountings and structural equipment for metallic gravity-discharge tanks - including aircraft refuelers used on public roads and inter-modal tanks (tank containers and tank swap bodies) for road and rail transport. It does not apply to fixed rail tank wagons.
Note: gravity-discharge tanks have no specified maximum working pressure, but operating pressures (e.g., from vapour recovery systems or breather devices) must not exceed the tank test pressure or 0.5 bar, whichever is higher.
Key topics and technical requirements
- Design limits and stress criteria
- Defines maximum membrane stress limits relative to material design strengths (fractional limits are specified in the standard; a distinct limit applies for tank containers and swap bodies).
- Materials and material verification
- Requirements for material selection, allowable values and how material properties feed into calculations.
- Openings, closures and pipework
- Mandatory provisions for filling/discharge openings, closures and pipe penetrations through the shell; service equipment passing through the shell is covered.
- Service and safety devices
- Tanks must be equipped with a breather device and a safety device to prevent loss of contents if the tank overturns; each compartment must be separately equipped.
- Manufacture, welding and testing
- Welding examination, manufacturing tolerances and testing requirements are aligned with referenced standards (updated references to EN 12972:2018).
- Design verification and annexes
- Methods for design verification and examples of welding details are included; Annex A has been made normative in the amendment.
- Operational considerations
- Thermal insulation must not hinder access to filling/discharge devices and safety valves.
Applications and who uses it
- Tank manufacturers and designers - to engineer compliant metallic gravity-discharge tanks.
- Certification bodies and inspectors - for type approval, testing and conformity assessment.
- Fleet operators and OEMs - particularly aircraft refuelers used on public roads and makers of inter-modal tanks for road/rail.
- Regulators and compliance teams - to ensure alignment with ADR/RID transport rules and national implementations.
Related standards
- EN 12972:2018 (weld examination, manufacturing tolerances)
- Referenced design codes such as EN 13445 (used in design verification references)
- ADR/RID provisions for service equipment and marking
Using EN 13094:2020/prA1 ensures safer, compliant metallic gravity-discharge tanks for the transport of low‑vapour‑pressure dangerous goods, improving operational safety, regulatory conformity and interoperability across road and rail transport systems.
