26、 vessels, referred to as vessel in this standard, designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock (see 1.6). It defines three types of vessel A, B and C (see table 1) corresponding to the current practice of European railway networks. 1.2 The vessels to

27、 this standard are: therefore does not apply to vessels with one or two flat ends or those made up of several compartments; g) calculated with a design pressure P (see 5.1.4.1.2); h) designed for a working temperature of between -40 OC and + 100 OC; i) fastened to the vehicles: 1) by straps for type

28、s A and B vessels; 2) by welded brackets for types B and C vessels. 1.3 In normal service, a momentary overpressure of 1 bar of the maximum working pressure is permitted (10 % of Ps). 1.4 This Part of this European Standard applies to the vessel proper, from the inlet connection to the outlet connec

29、tion and to all other connections and fittings belonging to the vessel. 1.5 This Part of this European Standard gives the requirements to be met for the calculation, design, fabrication, inspection during fabrication and certification of the and fittings for assembly to the vehicle. a) made from a s

30、ingle shell; b) made from non-alloy steel; c) fabricated by welding; d) used at a maximum working pressure of 10 bar; e) the (in bar) and the volume (in litre): 50 bar litres c PV I 10 O00 bar litres; f) made of a cylindrical part of circular cross-section called the shell with two outwardly dished
