7.                                          GENERAL TEST CONDITIONS
7.1.                                    The ambient temperature at the test site must be within the range of 0°C to 40°C.
7.2.                                    The following adjustments must be checked before commencing tests, and set to vehicle 'Manufacturer's' recommendations:
7.2.1.                              injection or ignition timing;
7.2.2.                              engine idle speed;
7.2.3.                              engine governed speed if adjustable governor is fitted; and
7.2.4.                              all brake adjustments.
7.3.                                    The tyres fitted to the vehicle must be of the size and type specified by the vehicle 'Manufacturer' as original equipment for the vehicle, and must be inflated to pressures not less than those recommended by the vehicle 'Manufacturer'.
7.4.                                    The 'Friction Elements' of the vehicle brakes must be of the make and grade specified by the vehicle 'Manufacturer'.
7.5.                                    Decelerations must be conducted on sections of a test track or roadway that meets the following requirements:
7.5.1.                              in the case of the Service Brake Fade Test, the surface must be substantially level and any effective upward average gradient between the start and end of each deceleration test section must not exceed one percent.  The requirements of this clause are deemed to be met if it is demonstrated that over the total number of brake applications of the Service Brake Fade Test sequence of clause 8.9, the total effective contribution to vehicle retardation of the deceleration test section's gradients is not greater than the vehicle retardation which would result from an average upward gradient of not more than one percent;
7.5.2.                              in the case of other deceleration tests, the upward gradient, if any, must not exceed one percent.
7.6.                                    Except when conducting burnishing procedures, decelerations must be conducted in a direction such that the component of wind velocity opposite to the direction of travel of the vehicle does not exceed 15 km/h.
7.7.                                    Where a test requires that the gear selector be in "drive" the transmission selector control must be in the control position recommended by the 'Manufacturer' as appropriate to the speed of the vehicle at the commencement of the deceleration mode.
7.8.                                    If the vehicle is not capable of attaining the initial speed requirement specified for a particular deceleration test, then, unless otherwise specified, the initial speed must be within 10 km/h of the 'Maximum Laden Vehicle Speed'.  The 'Average Deceleration' so required must be determined from the expressions:
a =  u2
     2s

         and

         where:
                  s = 'Stopping Distance', in metres
                  V =  initial speed, in km/h
                  K 1, K2 = constants, dependent on test and category, (see Table 3)
                  u  =  initial speed, in m/s
                  a = 'Average Deceleration', in m/s 2
7.9.                                    For
