147A  Exhaust emissions—diesel‑powered vehicles
 (1) This rule applies to registered passenger vehicles, omnibuses and goods vehicles:
 (a) powered by diesel engines; and
 (b) meeting the criteria for an M‑category or N‑category vehicle under the Australian Design Rules.
 (2) In this rule:
vehicle test mass for a vehicle means:
 (a) if the vehicle is a prime mover—half the sum of its tare mass and its GCM; or
 (b) in any other case—half the sum of its tare mass and its GVM.
Note: The vehicle test mass is the load applied to the dynamometer, while the vehicle is under test, to simulate half‑payload operation.
 (3) For subrule (4), a vehicle is taken to have been manufactured in the month shown on its compliance plate (that is, the plate, of the kind referred to in section 10A of the Motor Vehicle Standards Act 1989, affixed or taken to be affixed to the vehicle) as its month of manufacture.
 (4) When a vehicle is tested in accordance with the procedure described in Schedule 1 by means of test equipment that complies with the specification mentioned in subrule (5):
 (a) the vehicle must not emit oxides of nitrogen (NOx) at a rate (measured in grams of NOx emitted per kilometre travelled per tonne of the vehicle's test mass) greater than that specified for the vehicle according to its GVM rating and age in the following table:

Vehicle's GVM rating (t)               Rate of NOx emissions (g/km/t)
                                       Vehicle manufactured in December 1995 or earlier  Vehicle manufactured in January 1996 or later
not greater than 3.5                   1.5                                               1.5
more than 3.5 but not greater than 12  2.0                                               2.0
more than 12 but not greater than 25   2.0                                               1.5
more than 25                           1.5                                               1.2;

  and
 (b) the vehicle must not emit particles at a rate (measured in grams of particles emitted per kilometre travelled per tonne of the vehicle's test mass) greater than that specified for the vehicle according to its GVM rating and age in the following table:

Vehicle's GVM rating (t)               Rate of particle emission (g/km/t)
                                       Vehicle manufactured in December 1995 or earlier  Vehicle manufactured in January 1996 or later
not greater than 3.5                   0.23                                              0.23
more than 3.5 but not greater than 12  0.23                                              0.15
more than 12 but not greater than 25   0.08                                              0.05
more than 25                           0.07                                              0.03;

  and
 (c) the opacity of the exhaust gas emitted by the vehicle must not be greater than 25% (averaged over a DT 80 test cycle in the way described or referred to in the specification).
 (5) The specification for subrule (4) is that set out in the document known as Technical and functional specification for a diesel vehicle emissions measuring system, published by the National Road
