This document provides all of the information required in order to perform efficiently, and in standardized conditions, the determination, the declaration and the verification of noise emission values of refuse collection vehicles. The document ensures the reproducibility of the determination of noise emission values within the limits established for the accuracy grade of the basic standard used to determine noise emission values. This document specifies the noise measurement conditions for the types of RCVs defined and described in the standards of the EN 1501:2021 series. This document applies to machines which are manufactured after the date of approval of this document by CEN. Noise emissions of mobile waste and recycling containers are excluded.

This document specifies a method of comparing traffic noise on different road surfaces for various compositions of road traffic for the purpose of evaluating different road surface types. Sound levels representing either light or heavy vehicles at selected speeds are assigned to a certain road surface. The method is applicable to traffic travelling at constant speed, i.e. free-flowing conditions at posted speeds of 50 km/h and upwards. For conditions where traffic is not free flowing, such as at junctions and where the traffic is congested, the method is not applicable. A standard method for comparing the noise characteristics of road surfaces gives road and environment authorities a tool for establishing common practices or limits regarding the use of road surfaces meeting certain noise criteria. However, it is not within the scope of ISO 11819 (all parts) to suggest such criteria. The statistical pass-by (SPB) method is suitable for use for the following main purposes: — to classify road surfaces according to their influence on traffic noise (surface classification); — to assist in verifying conformity of production of road surfaces; — to evaluate acoustic performance of road surfaces throughout operation relative to new condition; — to evaluate the influence of different road surfaces on traffic noise at sites irrespective of condition and service time; — to evaluate acoustic performance of a road surface relative to a reference surface. Due to practical restrictions, the method cannot be applied at all possible locations. However, the backing board method can allow some locations to be tested that were not previously acceptable. Clause 5 gives a general description of the SPB method.

1 Scope This document specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N by using a semi anechoic chamber with a dynamometer installed. The specifications are intended to achieve an acoustical correlation between testing the exterior noise of road vehicles in a semi anechoic chamber and outdoor testing as described in ISO 362‑1. This document provides all necessary specifications and procedures for indoor testing to obtain results which are comparable to typical run-to-run variations of measurements in today’s type approval tests. This document provides a method designed to meet the requirements of simplicity as far as they are consistent with the reproducibility of results under the operating conditions of the vehicle. NOTE 1 The results obtained by this method give an objective measure of the noise emitted under the specified conditions of test. It is necessary to consider the fact that the subjective appraisal of the noise annoyance of different classes of motor vehicles is not simply related to the indications of a sound measuring system. As annoyance is strongly related to personal human perception, physiological human conditions, culture, and environmental conditions, there is a large variation and annoyance is therefore not useful as a parameter to describe a specific vehicle condition. NOTE 2 If measurements are carried out in rooms which do not fulfil the requirements stated i...
