This part of ISO 6855 specifies the general test requirements for measurement for the gaseous exhaust emissions from mopeds, and for determining the fuel consumption of mopeds as defined in ISO 3833. It is applicable to mopeds equipped with a spark ignition engine (four-stroke engine, two-stroke engine or rotary piston engine).<\/p>\n
