This document describes a test method for measuring in situ the sound absorption coefficient of road surfaces as a function of frequency in the range from 250 Hz to 4 kHz. Normal incidence is assumed. However, the test method can be applied at oblique incidence although with some limitations (see Annex F). The test method is intended for the following applications: —    determination of the sound…

This document specifies the measurement and evaluation methods for gaseous and particulate exhaust emissions from reciprocating internal combustion engines (RIC engines) in the field. This document is applicable when the emissions from RIC engines used in non-road machinery, industrial equipment, marine installations, generating sets, diesel rail traction or similar machinery applications need to…

This document provides injury risk curves to assess occupant protection in frontal impact using the 50th percentile THOR metric dummy (THOR-M 50). Injury risk curves developed specifically for the THOR dummy are chosen preferably, however, when not available, the applicability of the PMHS injury risk curve is evaluated with regard to the dummy biofidelity. Finally, when possible, a field…

This document specifies performance requirements and test procedures for systems capable of warning the subject vehicle driver of a potential crossing-path collision with other vehicles at intersecting road segments. Vehicle-to-vehicle intersection collision warning systems (VVICW) rely on vehicle-to-vehicle (V2V) communications and relative positioning between the subject vehicle and crossing-…

This document specifies the essential characteristics of a test track surface intended to be used for measuring rolling sound emission of vehicles and their tyres. The surface design given in this document —    produces consistent levels of tyre or road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing, —    minimizes inter-site…
