20、lene vehicles) in European countries. The term “acetylene battery vehicle“ covers a number of different systems which connect acetylene cylinders (see EN 1800) or acetylene bundles (see EN 12755) in a single unit for the purpose of storage, transport and use of acetylene.

32、form to prEN 13807 for the design, manufacture, identification and testing or to an equivalent standard. Different porous masses and different solvents may be adopted provided that each cylinder in the vehicle contains the same porous mass and solvent. The manifold shall be equipped with all the nec
33、essary devices (e.g. valves, flash-back arrestors, flow cut-off devices and measuring devices) to ensure safe operation during transport, storage, filling and emptying. 4.3 Type of solvent The number of filling cycles before replenishment of solvent will depend on the type of solvent (acetone or dim
34、ethyl formamide (DMF) and shall be determined for an acetylene vehicle type B in accordance with EN 1801 (for single cylinders) or EN 12755 (for bundles) to ensure that no cylinder on the vehicle is filled if it contains less than the specified minimum quantity of solvent. 4.4 Identification It shal
35、l be verified that: a) the acetylene vehicle has any necessary approvals; b) the acetylene vehicle is permitted to be filled in the country of the filling station; c) the cylinders have not passed their statutory test period.

37、c) type of porous mass; d) type of solvent; e) maximum gross weight. In addition, for acetylene vehicles type B only: f) date of the next periodic inspection of the cylinders or bundles; g) tare weight of acetylene vehicle (see 3.4); h) the minimum specified quantity of solvent; i) the number of con
38、secutive fillings since the last replenishment of solvent, if applicable. 4.5.3 Design data and records a) reference identifying acetylene vehicle and type; b) total number of cylinders or bundles; c) size and identification number of all cylinders or bundles; d) operating procedures including filli
39、ng and emptying; e) flow diagram and emergency instructions; f) records of pressure tests and maintenance; g) records of solvent loss from cylinders and bundles. 4.5.4 Other information a) name or identification of the manufacturer of the acetylene vehicle; b) name or identification of the owner of

41、nspection before filling shall be carried out on acetylene vehicles in order to establish that: a) the cylinders have no apparent serious defects, as defined in EN 12754; b) the frames have no apparent serious defects; c) the manifold has no apparent serious defects; d) the cylinder valves and cylin
42、der fittings have no apparent serious defects; e) the main inlet/outlet and/or the connection fittings are in a satisfactory condition and function satisfactorily; f) the vehicle is labelled in accordance with all applicable statutory requirements; g) the cylinders are not overdue for periodic inspe
43、ction; h) the prescribed number of refills has not been exceeded (see 4.3), if applicable. Additional requirements for acetylene vehicle type B: i) the determination of residual gas and solvent loss in accordance with the filling procedure (see 5.2.3) has brought no negative result; j) all cylinder
44、valves and isolation shut-off valves are open; NOTEIf individual valves of cylinders are found closed, care should be taken and the reason should be investigated before proceeding with filling. k) before connecting the filling hose, the vehicle shall be immobilised so that it cannot be moved whilst
45、the filling hose remains connected; l) an earthing connection has been made between the filling point and the acetylene vehicle. 5.2 Filling procedure for acetylene vehicles 5.2.1 Filling pressure The maximum filling pressure for acetylene vehicles shall not exceed 25 bar (gauge). 5.2.2 Filling proc
