Division 1 Testing methodology — Introduction

In order to determine the CO₂ emission reductions that can be attributed to the efficient exterior lighting with the use of light emitting diodes (LED) in an M1 vehicle, it is necessary to establish the following:

1. (a)

   the testing conditions;

2. (b)

   the test procedure;

3. (c)

   the formulae for calculating the CO₂ savings;

4. (d)

   the formulae for calculating the standard deviation;

5. (e)

   the determination of the CO₂ savings for the certification by type approval authorities.
