Simple unfired pressure vessels designed to contain air or nitrogen - Part 4: Aluminium alloy pressure vessels designed for air brake equipment and auxiliary pneumatic equipment for railway rolling stock
1.1 This document applies to simple unfired aluminium alloy pressure vessels manufactured in series, referred to as “vessel” in this document, designed for air brake equipment and auxiliary pneumatic equipment for railway rolling stock.
1.2 The vessels to this document are:
a) made from a single shell;
b) made from aluminium alloy;
c) fabricated by welding;
d) used at a maximum working pressure up to15 bar;
e) the product of the maximum working pressure (in bar) and the volume (in L): 50 bar L < PS∙V ≤ 10 000 bar L;
f) made of a cylindrical part of circular cross-section called the shell with two outwardly dished torispherical ends, that is two dished ends with the same axis of rotation. This document 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 5.1.4.2);
h) designed for a working temperature of between −50 °C and +100 °C [+65 °C for certain grades of aluminium alloy (see 4.1.2)];
i) fastened to the vehicles by straps.
1.3 This document applies to the vessel proper, from the inlet connection to the outlet connection and to all other connections and fittings belonging to the vessel.
1.4 This document gives the requirements to be met for the calculation, design, fabrication, inspection during fabrication and certification of the vessel, and fittings for assembly to the vehicle.
This document gives:
a) in Annex B, recommendations for assembly to the vehicles;
b) in Annex C, recommendations for the service surveillance of vessels.
The requirements of this document apply to vessels designed to be fitted to rail vehicles.
