Heavy Vehicle (Vehicle Standards) National Regulation

This section applies to a heavy motor vehicle—

powered by a diesel engine; and

meeting the criteria for a passenger vehicle including omnibuses and goods vehicles as defined under the ADRs.

For the purposes of subsection (3), a vehicle is taken to have been manufactured in the month shown on its identification plate as its month of manufacture.

When a vehicle is tested in accordance with the procedure described in section 97—

the vehicle must not emit oxides of nitrogen (NOx) at an oxides emission rate greater than that stated for the vehicle according to its GVM rating and age in the following table; and

the vehicle must not emit particles at a particle emissions rate greater than that stated for the vehicle according to its GVM rating and age in the following table; and

the opacity of the exhaust gas emitted by the vehicle must not be greater than 25%, averaged over a DT80 test cycle in the way described or mentioned in the test procedure stated in section 97 that complies with the requirements in section 98.

In this section—oxides emission rate means the rate measured in grams of NOx emitted per kilometre travelled per tonne of the vehicle’s test mass.particle emissions rate means the rate measured in grams of particles emitted per kilometre travelled per tonne of the vehicle’s test mass.vehicle’s test mass means—

if the vehicle is a prime mover—half the sum of its tare mass and its GCM; or

in any other case—half the sum of its tare mass and its GVM.

Note—The vehicle’s test mass is the load applied to the dynamometer, while the vehicle is under test, to simulate half payload operation.
