Road vehicles. Road load - Determination under reference atmospheric conditions Ingestion-build-105964 testing and approval of separative1 Scope This part of ISO 10521 specifies methods of determining the road load of road vehicles for subsequent test purposes, for example, fuel consumption tests or exhaust emission measurements. This determines the road load of a vehicle running on a level road under reference atmospheric conditions. It is achieved by either the coastdown method, the torquemeter method or the wind tunnel chassis dynamometer method. This part of ISO 10521 is applicable
