UN 2487 Phenyl isocyanate RID 2025 (Shortinfo)

The degree of filling prescribed in 4.2.1.9.3 shall not be exceeded: Degree of filling = 95 / (1 + alpha x (tr - tf)) where alpha = mean coefficient of cubical expansion of the liquid between tf and tr; tr = maximum mean bulk temperature during carriage [°C]; tf = mean temperature of the liquid during filling [°C].

The protective caps of closures shall be locked during carriage.

Tanks shall not be used for the carriage of foodstuffs, articles of consumption or animal feeds.

Tank-wagons, demountable tanks and battery-wagons: Procedure following activation of energy absorption elements When energy absorption elements have undergone plastic deformation in accordance with 6.8.4, special provision TE 22, the tank-wagon or batterywagon shall, after undergoing an inspection, be removed to a repair workshop immediately. If the loaded tank-wagon or loaded battery-wagon is capable of absorbing the shocks of a collision that might occur in normal conditions of rail transport, e.g. after the energy absorption buffers fitted have been replaced with normal buffers or after the damaged energy absorption elements have been temporarily blocked off, the tank-wagon or battery wagon may, after undergoing an inspection, be moved for the purpose of emptying and finally to a repair workshop. The information that the energy absorption elements are not working shall be made available with the tank-wagon or battery-wagon. Tank-containers, tank swap bodies and MEGCs: (Reserved)

The closures shall be protected with lockable caps.

Tank-wagons, demountable tanks and battery-wagons: In order to reduce the extent of damage in the event of a collision shock or accident, each end of tank-wagons for substances carried in the liquid state and gases or battery-wagons shall be capable of absorbing at least 800 kJ of energy by means of elastic or plastic deformation of defined components of the subframe or by means of a similar procedure (e.g. crash elements). The energy absorption shall be determined in relation to a collision on a straight track. Energy absorption by means of plastic deformation shall only occur in conditions other than those encountered during normal conditions of rail transport (impact speed higher than 12 km/h or individual buffer force greater than 1500 kN). Energy absorption of not more than 800 kJ at each end of the wagon shall not lead to transfer of energy to the shell which could cause visible, permanent deformation of the shell. The requirements of this special provision are deemed to be met if crashworthy buffers (energy absorption elements) that conform to clause 7 of standard EN 15551:2009 + A1:2010 (Railway applications - Railway rolling stock - Buffers) are used and if the resistance of the wagon body satisfies clause 6.3 and sub clause 8.2.5.3 of standard EN 12663-2:2010 (Railway applications - Structural requirements of railway vehicle bodies - Part 2: Freight wagons). The requirements of this special provision are deemed to be met by tank-wagons with an automatic coupling device equipped with energy absorption elements capable of absorbing at least 130 kJ at each end of the wagon. Tank-containers, tank swap bodies and MEGCs: (Reserved)
