International Standard
43.060.01 Internal combustion engines for road vehicles in general
This International Standard is applicable to heavy-duty road vehicle engines subject to regulations as regards their
exhaust emissions at the time of their certification. Mopeds, motorcycles, passenger cars and non-road vehicles
are not within its scope.
This International Standard defines the criteria making it possible to group those engines of the same manufacturer
having, by design, similar regulated exhaust emission characteristics (gaseous and particulate pollutants, as well
as smoke) within a family or families.
It defines the parameters necessitating the carrying out of different groupings, leaving open to the manufacturer the
latitude to carry out groupings of lower size.
This International Standard defines the procedure for selecting from within each engine family the parent engine,
the specific characteristics of which will probably make it more difficult to produce a low level of exhaust emissions.
