the device is justified in terms of protecting the engine against damage or accident and for safe operation of the vehicle;
                  (b) The device does not function beyond the requirements of engine starting;
or
                  (c) The conditions are substantially included in the test procedures for verifying evaporative emissions and average tailpipe emissions.
6.1.10. Division by zero
In the case that the data input to a formula in this regulation justifiably leads to division by zero, e.g. when an OVC-HEV consumes zero fuel under charge-depleting conditions, good engineering judgement shall be applied.
6.2. Test procedure
Table A specifies the various test requirements for type approval of a vehicle.

   1  Specific test procedures for hydrogen vehicles will be defined at a later stage.
   2  Particulate mass and particle number limits and respective measurement procedures shall apply only to vehicles with direct injection engines
   3  When a bi-fuel vehicle is combined with a flex fuel vehicle, both test requirements are applicable.
   4  Only NOx emissions shall be determined when the vehicle is running on hydrogen.
      5  For Level 1A only - Particulate mass and particle number limits and respective measurement procedures shall not apply. For Level 1B only - In the case that a mono-fuel gas vehicle has a petrol tank it shall also be tested using the applicable petrol reference fuel
   6  For Level 1B, if the mono-fuel gas vehicle does have a petrol tank "Yes", if the mono-fuel gas vehicle
