1.1 This standard specifies standard reference conditions and methods of declaring the power, fuel consumption, lubricating oil consumption and test methods for internal combustion engines in commercial production using liquid or gaseous fuels. It applies to:
a) reciprocating internal combustion (RIC) engines (spark-ignition or compression-ignition engines) but excluding free piston engines;
b) rotary piston engines.
These engines may be naturally aspirated or pressure-charged either using a mechanical pressure-charger or turbocharger.
1.2 This standard applies to engines used for:
a) land, rail-traction and marine use as defined in GB/T 6072.1;
b) the propulsion of automotive vehicles as defined in ISO 1585 and ISO 2534;
c) motorcycles as defined in ISO 4106;
d) the propulsion of agricultural tractors and machines as defined in ISO 2288;
e) the propulsion of earth-moving machinery as defined in ISO 9249;
f) the propulsion of recreational craft or other small marine craft up to 24m hull length as defined in ISO 8665.
This standard may be applied to engines used to propel road construction machines, industrial trucks, and for other applications where no suitable standard for these engines exists.
1.3 Individual requirements for a particular engine application are given in the relevant “Satellite” standard. In order to completely specify the requirements relevant to a particular engine application this “Core” standard shall only be used in conjunction with the relevant “Satellite” standard.
