      1.4. Tolerance

       Tolerances are given in figure 4.

      Figure 4

      Speed tolerance

       Tolerances on speed (± 2 km/h) and on time (± 1 s) are geometrically combined at each point as represented in figure 4.

       Below 50 km/h, deviations beyond this tolerance are permitted as follows:

       (a) at gear changes for a duration less than 5 seconds,
          (b) and up to five times per hour at other times, for a duration less than 5 seconds each.

       The total time out of tolerance has to be mentioned in the test report.

       Over 50 km/h, it is accepted to go beyond tolerances provided the accelerator pedal is fully depressed.

      2. TEST METHOD

      2.1. Principle

       The test method described hereafter allows the electric energy consumption, expressed in Wh/km, to be measured:

      2.3. Vehicle

      2.3.1. Condition of the vehicle

      2.3.1.1. The vehicle tyres shall be inflated to the pressure specified by the vehicle manufacturer when the tyres are at the ambient temperature.

      2.3.1.2. The viscosity of the oils for the mechanical moving parts shall conform to the specification of the vehicle manufacturer.

      2.3.1.3. The lighting and light-signalling and auxiliary devices shall be off, except those required for testing and usual day-time operation of the vehicle.

      2.3.1.4. All energy storage systems available for other than traction purposes (electric, hydraulic, pneumatic, etc.) shall be charged up to their maximum level specified by the manufacturer.

      2.3.1.5. If the batteries are operated above the ambient temperature, the operator shall follow the procedure recommended by the car manufacturer in order to keep the temperature of the battery in the normal operating range.

       The manufacturer's agent shall be in a position to attest that the thermal management system of the battery is neither disabled nor reduced.

      2.3.1.6. The vehicle must have undergone at least 300 km during the seven days before the test with those batteries that are installed in the test vehicle.

      2.4. Operation mode

       All the tests are conducted at a temperature of between 20 C and 30 C.

       The test method includes the four following steps:

       (a) Initial
