Division 1 INTRODUCTION

In order to determine the CO₂ savings that can be attributed to the use of a 12 V efficient alternator in a passenger car and light commercial vehicle with internal combustion engine powertrain, it is necessary to specify the following:

1. (1)

   the testing conditions;

2. (2)

   the test equipment;

3. (3)

   the procedure to determine the total efficiency;

4. (4)

   the procedure to determine the CO₂ savings;

5. (5)

   the procedure to determine the uncertainty of the CO₂ savings.
