This document specifies the measurement method and conditions to obtain reproducible and comparable noise levels on-board all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called "unit", except for track maintenance vehicles in working modes.

NOTE For constant speed tests the concept of "comparability" needs further caution, as this term is used as well to classify the measurement precision grade related to track roughness and track decay rates given in this document. Nevertheless, the measurement may be acceptable as type test on a track of controlled acoustic quality, but not compliant to the track specification given in this document.

This document is applicable to type testing. It does not include all the instructions to carry out monitoring testing or evaluation of noise exposure of passengers or drivers over a whole journey.

This document is not applicable to guided buses.

It provides measurement procedures for vehicle interior noise:

— when the vehicle is moving at constant speed;

— when the vehicle is stationary;

— when the vehicle is accelerating or decelerating;

— in the driver's cab when an external warning horn is sounding.

NOTE In general, a vehicle type acceptance test would require only a selected subset of these tests to be performed.

It does not provide measurement procedures for:

— audibility or intelligibility of any audible signals;

— assessment of warning devices other than warning horns.

The assessment of noise exposure of train crew due to operational conditions is not in the scope of this document.

The results may be used, for example:

— to characterise the noise inside these units;

— to compare the internal noise of various units on a particular track section;

— to collect basic source data for units.

The test procedures specified in this document are of engineering grade (grade 2), that is the preferred one for noise declaration purposes, as defined in EN ISO 12001. If test conditions are relaxed for example as done for monitoring of in-service trains, then the results are no longer of engineering grade.

The procedures specified for accelerating and decelerating tests are of survey grade.

1.1 This document is applicable to simple unfired aluminium alloy pressure vessels, referred to as "vessel" in this document, designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock (see 1.6).

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 of 10 bar;

e) the product of the maximum working pressure (in bar) and the volume (in litre): 50 bar litres < PV ≤ 10 000 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 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;

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 In normal service, a momentary overpressure of 1 bar of the maximum working pressure is permitted (10 % of PS).

1.4 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.

1.5 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.

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 document gives:

a) in Annex B, recommendations for assembly to the vehicles;

b) in Annex C, recommendations for the service surveillance of vessels.

1.6 The requirements of this document 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, etc.).
