BS ISO 1585 This document specifies a method for testing engines designed for automotive vehicles. It applies to the evaluation of their performance with a view, in particular to presenting curves of power and specific fuel consumption at full load as a function of engine speed.It applies only to net power assessment.This document concerns internal combustion engines used for propulsion of passenger cars, trucks and other motor vehicles, excluding motorcycles, mopeds and agricultural tractors normally travelling on roads, and included in one of the following categories:一reciprocating internal combustion engines (sparkignition or compression-ignition) but excluding free piston engines; rotary piston engines.These engines can be naturally aspirated or pressure-charged, either using a mechanical supercharger or turbocharger.

Vocabulary of components and systems-Part 3: Valves, camshaft drives and actuating mechanisms.5.3.2 Performance data shall be obtained under stabilized operating conditions, with an adequate fresh air supply to the engine. Engines shall have been run-in, started and warmed up in accordance with the manufacturer’s recommendations. Combustion chambers may contain deposits, but in limited quantity. Test conditions such as inlet air temperature shall be selected as near to reference conditions (see 6.2) as possible in order to minimise the correction factor.The lubricant temperature shall be measured at the oil gallery inlet or the cooler outlet if fitted,unless some other measuring location is specified by the manufacturer. The temperature shall be maintained within the limits specified by the manufacturer.BS ISO 1585 pdf download.
