EN 13807:2017 (E) 5 Introduction For certain applications, transport units known as battery vehicles and MEGCs of non UN pressure receptacles are used to supply greater volumes of gas in a single unit. A battery vehicle is a vehicle containing pressure receptacles which are linked to each other by a manifold and permanently fixed to a transport unit. General requirements for the design, construction, equipment, type approval, inspections and tests and marking of battery vehicles are given in Chapter 6.8 and 9 of the ADR. Some specific or additional requirements are given in this European Standard. In standards, weight is equivalent to a force, expressed in Newton. However, in common parlance (as used in terms defined in this European Standard), the word “weight” continues to be used to mean “mass”, but this practice is deprecated (ISO 80000-4). In this European Standard, the unit bar is used, due to its universal use in the field of technical gases. It should, however, be noted that bar is not an SI unit, and that the according SI unit for pressure is Pa (1 bar = 105 Pa = 105 N/m2). Pressure values given in this European Standard are given as gauge pressure (pressure exceeding atmospheric pressure) unless noted otherwise. Where there is any conflict between this European Standard and any applicable regulation, the regulation always takes precedence. SIST EN 13807:2017



EN 13807:2017 (E) 6 1 Scope This European Standard specifies the requirements for the design, manufacture, identification and testing of battery vehicles and multiple-element gas containers (MEGCs) containing cylinders, tubes or bundles of cylinders.

Where higher or lower service temperatures are required, any additional requirements shall be agreed between the manufacturer and purchaser. NOTE 1 Local temperature conditions can necessitate higher or lower service temperatures. NOTE 2 Additional requirements can be required for adapted equipment and/or tests. Materials for parts which are in contact with the gas shall be selected in accordance with the relevant European Standards on compatibility (i.e. the EN ISO 11114- series). SIST EN 13807:2017



EN 13807:2017 (E) 10 For battery vehicles and MEGCs which are filled by weight, the tare used as a reference for filling shall be clearly identified taking into account removable components, where applicable. For acetylene battery vehicles, additional requirements apply on certain subjects. These are given in normative Annex A. 4.2 Mounting 4.2.1 Stability (for battery vehicles only) The overall width of the ground-level bearing surface (distance between the outer points of contact with the ground of the right-hand tyre and the left-hand tyre on the same axle) shall be at least 90 % of the height of the centre of gravity of the laden battery vehicle. In an articulated vehicle the weight on the axles of the load carrying unit of the laden semi-trailer shall not exceed 60 % of the nominal total laden weight of the complete articulated vehicle. 4.2.2 Attachment of pressure receptacles to a chassis Attachments shall, at the maximum gross weight, be capable of absorbing the stresses equal to those exerted by: — in the direction of travel — twice the gross weight; — horizontally at right angles to the direction of travel — the gross weight, where the direction of travel is not clearly determined twice the gross weight in each direction; — vertically upward — the gross weight; — vertically downward — twice the gross weight. Values for gross weight shall be calculated independently of each other. Under each force, the stress at the most severely stressed point of the pressure receptacles and their fastenings shall not exceed the value of 77 % of the yield stress, Re, of the material used. 4.2.3 Pressure receptacle supports Pressure receptacles shall be secured in a manner that prevents both movement in relation to the chassis and the concentration of local stresses. In particular, the bottom pressure receptacles of a stack, and pressure receptacles to which clamping forces are applied, shall not be subjected to point loads which result in concentrations of high local stress. Suitable means shall be provided to distribute this loading. The pressure receptacles shall have their weight supported directly from their bodies and not from separate valve guards or valve protection caps unless these are specifically designed for this purpose (e.g. composite cylinders). The supports and holding down straps shall be such that they minimize the risk of corrosion to the pressure receptacles. Absorbent materials used in supports may only be used if they have been treated to eliminate water absorption. EXAMPLE Examples of suitable materials are water resistant belting and rubber. Composite cylinders and tubes shall be fitted in the supports such that a direct contact between individual cylinders or tubes is minimized. SIST EN 13807:2017



EN 13807:2017 (E) 11 4.2.4 Impact protection 4.2.4.1 For battery vehicles There are two types of impact protection: a) Rear end protection An arrangement shall be fitted at the rear of the battery vehicle to provide adequate protection to the rear pipework and fittings to prevent accidental leakage of product in the event of a rear impact. The arrangement should meet at least the impact requirements for a rear under-run protective device required by EU directives (see 70/221/EEC). The width of this arrangement shall be not less than that of the rear under-run protective device and not less than that of the pipework and fittings. There shall be a clearance of at least 100 mm between the arrangement and the rearmost point of the piping, fittings and valves under gas pressure during transport. b) Rollover protection Manifolds shall be designed such that they are protected from impact in the event of a battery vehicle rolling onto its side or upside down. 4.2.4.2 For MEGCs An arrangement shall be fitted on the MEGC to provide adequate protection for pipework and fittings to prevent accidental leakage of product in the event of an end impact. The arrangement shall meet at least the impact requirements of an ISO frame in accordance with the relevant provisions of ISO 1496-3. 4.3 Pressure receptacles Pressure receptacles within a battery vehicle and MEGCs shall be suitable for the intended gas service. They shall have the same test pressure and follow the equivalent appropriate European Standards for the individual type of pressure receptacle. Composite receptacles shall be protected from ultraviolet radiation according to the manufacturer’s instructions. This may be achieved by protection of individual cylinders or tubes or by a protection for the whole battery vehicle. 4.4 Valves and fittings 4.4.1 Either a pressure receptacle valve or fitting shall be fitted into each pressure receptacle’s inlet connection. If a valve is used, it shall conform to EN ISO 10297. For acetylene battery vehicles, A.2.6 applies. They shall be suitable for the gas service and pressure for which the battery vehicle and MEGCs is intended. They shall be compatible with the inlet thread of the pressure receptacles. 4.4.2 Pressure receptacles of a battery-vehicle and MEGCs intended for the carriage of flammable gases shall be combined in groups of not more than 5 000 l which are capable of being isolated by a shut-off valve. For acetylene battery vehicles, A.2.6 applies. Each pressure receptacle, including
