1 Scope
This Standard specifies the measurement methods of net power for automotive engine.
This Standard applies to the curve of net power of Categories M and N automotive engines relative to rotational speed change.
This Standard applies to reciprocating piston engines (spark ignition type and compression ignition type) or Wankel engines (spark ignition type and compression ignition type), but excludes free piston engines.
