35.4.                                GENERAL TEST CONDITIONS
35.4.1.                          The ambient temperature at the test site shall be within the range of 0 to 40 °C.
35.4.2.                          The following adjustments shall be checked before commencing tests, and set to vehicle 'Manufacturer's' recommendations:
35.4.2.1.                    injection or ignition timing;
35.4.2.2.                    engine idle speed;
35.4.2.3.                    engine governed speed if adjustable governor is fitted; and
35.4.2.4.                    all brake adjustments.
35.4.3.                          The tyres fitted to the vehicle shall be of the size and type specified by the vehicle 'Manufacturer' as original equipment for the vehicle, and shall be inflated to pressures not less than those recommended by the vehicle 'Manufacturer'.
35.4.4.                          The 'Friction Elements' of the vehicle brakes shall be of the make and grade specified by the vehicle 'Manufacturer'.
35.4.5.                          Decelerations shall be conducted on sections of a test track or roadway that meets the following requirements:
35.4.5.1.                    in the case of the Vehicle Service Brake Fade Test, the surface shall be substantially level and any effective upward average gradient between the start and end of each deceleration test section shall not exceed one per cent. The requirements of this clause shall be deemed to be met if it is demonstrated that over the total number of brake applications of the Vehicle Service Brake Fade Test sequence of clause 35.5.9.1 the total effective contribution to vehicle retardation of the deceleration test section gradients is not greater than the vehicle retardation which would result from an average upward gradient of not more than one per cent;
35.4.5.2.                    in the case of other deceleration tests, the upward gradient, if any, shall not exceed one per cent.
35.4.6.                          Except when conducting burnishing procedures, decelerations shall 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.
35.4.7.                          Where a test requires that the gear selector be in "drive" the transmission selector control shall be in the control position recommended by the 'Manufacturer' as appropriate to the speed of the vehicle at the commencement of the deceleration mode.
35.4.8.                          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 shall be within 10 km/h of the 'Maximum Laden Vehicle Speed'. The 'Average Deceleration' so required shall be determined from the expressions:
and
where:
s = 'Stopping Distance 35/00', in metres
V = initial speed, in km/h.
K1, K2 = constants, dependent on test and category, see chart below
u = initial speed, in m/s
a = 'Average Deceleration', in m/s2
35.4.9.                          For all effectiveness, secondary brake and partial failure tests, no part of the vehicle shall move outside
