    *1 For petrol or LPG, particulate mass and particle number limits shall apply only to vehicles with direct injection engines.
    *2 Except vehicles having engine displacement less than or equal to 0.660 litre, vehicle length less than or equal to 3.40m, vehicle width less than or equal to 1.48m, and vehicle height less than or equal to 2.00m, seats less than or equal to 3 in addition to a driver, and payload less than or equal to 350kg.
   *3 Vehicles having engine displacement less than or equal to 0.660 litre, vehicle length less than or equal to 3.40m, vehicle width less than or equal to 1.48m, and vehicle height less than or equal to 2.00m, seats less than or equal to 3 in addition to a driver, and payload less than or equal to 350kg.
   *4 As there are no assigned deterioration factors for compression ignition vehicles, manufacturers shall use the whole vehicle ageing durability test procedures to establish deterioration factors.

              6.7.2.1. This paragraph is applicable for Level 1B only
              In the case that the limit value is different from the value defined in Table 3b, the assigned additive deterioration factor shall be calculated using the following equation and shall be rounded according to approval authority instruction:
              the assigned additive deterioration factor = Limit value * A * (Useful life – 3,000)/(80,000 – 3,000)
