Reciprocating Internal Combustion Engines--Performance--Part 1: Standard Reference Conditions, Declarations of Power, Fuel and Lubricating Oil Consumptions, and Test Methods(Cancelled Apr 2005)
This part of ISO 3046 specifies standard reference conditions and methods of declaring the power, fuel consumption, lubricating oil consumption, and test methods for reciprocating internal combustion (RIC) engines in commercial production using liquid or gaseous fuels. Where necessary, individual requirements are given for particular engine applications.
This part of ISO 3046 covers RIC engines for land, rail-traction, and marine use, excluding engines used to propel agricultural tractors, road vehicles, and aircraft.
This part of ISO 3046 may be applied to engines used to propel road construction and earthmoving machines, industrial trucks, and for other applications where no suitable International Standard for these engines exists.
This part of ISO 3046 may be applied to tests on a test bed at the manufacturer's works and to tests on site.
Rationale: J3046-1 is now an obsolete recreational power rating standard and should be cancelled as an SAE standard.
The current applicable International power rating standard for small crafts are ISO 15550 and ISO 8665
