6.3

Performance prediction. SAE Truck Ability Prediction Procedure computations and

computations for low speed and maximum geared speed will be required by the contract. The

SAE Work Sheet Item 1 should include vehicle model number, engine model number, and vehicle type, class and model. Unless other conditions are cited in the contract, computations should be made for normal atmospheric pressure, normal ambient air temperature, and still dry air. The factors to be used in predicting truck ability (see 3.3.1.1) are established as follows for the corresponding SAE Truck Ability Prediction Procedure Tables:

Table 1 - Tire Factor. This factor must relate to the size of tires furnished by the contractor in accordance with this specification.

Table 2 - Altitude Factor. 1.00

Table 3 - Rolling Factor. 1.613

Table 4 - Area Factor. 0.225

Table 5 - Velocity Factor. 250.0
