Internal combustion engines. Engine weight (mass) declaration has-hardcopy Pollutant levels in surface water1 Scope This International Standard specifies how to make a declaration of the engine weight (mass) for internal combustion engines. For the purposes of this International Standard, the word weight is used as the direct equivalent of the word mass. This International Standard applies to reciprocating internal combustion engines (spark ignition or compression ignition engines) but excluding free piston engines, and rotary piston engines. These engines
