适用范围：1 This Part of this European Standard is applicable to simple unfired aluminium alloy pressure vessels, referred to as 'vessel' in this standard, designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock (see 1.6). 2 The vessels to this standard are: a) made from a single shell; b) made from aluminium alloy; c) fabricated by welding; d) used at a maximum working pressure of 10 bar; e) the product of the maximum working pressure (in bar) and the volume (in litre): 500 bar litres < PV ≤ 10000 bar litres; 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 standard 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 ℃ and + 100 ℃ [ + 65 ℃ for certain grades of aluminium alloy (see 4.1.1)]; j) fastened to the vehicles by straps; 3 In normal service, a momentary overpressure of 1 bar of the maximum working pressure is permitted (10% of Ps). 4 This Part of this European Standard applies to the vessel proper, from the inlet connection to the outlet connection and to all other connections and fittings belonging to the vessel. 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 vessel, and fittings for assembly to the vehicle. These requirements cannot be written in sufficient detail to ensure good workmanship or proper construction. Each manufacturer is therefore responsible for taking every necessary step to make sure that the quality of workmanship and construction is such as to ensure compliance with good engineering practice. This Part of this standard gives: a) in annex F, recommendations for assembly to the vehicles; b) in annex G, recommendations for the service surveillance of vessels. 6 The requirements of this Part of this European Standard apply to vessels designed to be fitted to rail vehicles used on the main national networks, urban networks, underground railways, trams, private networks (regional railways, company railways, . . . ).
