ISO/TC 22/SC 38/WG 1 - Pollution and energy

This document specifies a basic measurement method by using a permeation test procedure for evaporative emissions from motorcycles. It is applicable to motorcycles equipped with a fuel tank to store liquid high volatile fuel and with a spark ignition engine (four-stroke engine, two-stroke engine or rotary piston engine).

This document specifies a basic measurement method by using the SHED (Sealed Housing for Evaporative Determination) test procedure for evaporative emissions from motorcycles. It is applicable to motorcycles equipped with a spark ignition engine (four-stroke engine, two-stroke engine or rotary piston engine).

ISO 17479:2013 specifies methods for the direct measurement of the concentration of gaseous exhaust emissions from motorcycles as defined in ISO 3833 during inspection or maintenance. The results measured by this International Standard show the concentration of gaseous exhaust emissions in the no-load engine operating condition. It is applicable to motorcycles having spark ignition engines (four-stroke engines or two-stroke engines). This methods can be used, either totally or partially, for a) periodic inspections in official garages, b) official roadside checks, and c) maintenance and diagnostic operations.

ISO 6460-1:2007 specifies the general test requirements for measurement for the gaseous exhaust emissions from motorcycles, and for determining the fuel consumption of motorcycles as defined in ISO 3833. It is applicable to motorcycles equipped with a spark ignition engine (4-stroke engine, 2-stroke engine or rotary piston engine) or a compression ignition engine.
