This document specifies a chassis dynamometer test procedure to measure the exhaust emissions and the electric energy and fuel consumption for the vehicles. This document applies to vehicles with the following characteristics:

— the vehicles are classified as passenger cars or light duty trucks, as defined in the relevant regional ADT standard;

— the nominal energy of the rechargeable energy storage system (RESS) is at least 2 % of the total energy consumption over an applicable driving test (ADT);

— internal combustion engine (ICE) only using liquid fuels (for example, gasoline and diesel fuel).

NOTE 1 In the case of the vehicles with ICE using other fuel [for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), hydrogen], this document can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.

This document proposes procedures for correcting the measured emissions and fuel consumption of hybrid electric vehicles (HEVs), in order to obtain the values when the battery state of charge (SOC) of the RESS does not remain the same between the beginning and the end of an ADT.

It can also be applied to measurement procedures for exhaust emissions and fuel consumption of externally chargeable HEVs when a vehicle is not externally charged and operated only in the charge sustaining (CS) state, as described in ISO 23274‑2.

NOTE 2 For CS state, see ISO 23274‑2.

This International Standard specifies a method for comparing simulation results from a mathematical vehicle model to measured test data for an existing vehicle combination’s lateral stability according to driving tests as specified in ISO 14791. The comparison is made for the purpose of validating the simulation tool for this type of test. A complete validation should comprise the comparison for at least one tested vehicle and one variant of this vehicle, covered by a parameter variation in the vehicle model.

The standard applies to heavy vehicles, including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3.5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).

This International Standard specifies a method for comparing simulation results from a mathematical vehicle model to measured test data for an existing vehicle according to steady-state circular driving tests as specified in ISO 14792:2011. The comparison is made for the purpose of validating the simulation tool for this type of test. The standard applies to heavy vehicles, including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with a maximum weight above 3.5 tonnes and buses and articulated buses with a maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
