6.3 Performance prediction. Completed copies of SAE Truck Ability Prediction

Procedure form, and computation for low speed requirement for the vehicle furnished under

contract, should be submitted as specified in the contract. Unless other conditions are cited in the

contract, computations should be made for normal atmospheric pressure, normal ambient air

temperature, and in still, dry air. The factors to be used in predicting vehicle ability (see 3.3) are

established as follows for the corresponding SAE J688 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.

- Chassis friction horsepower. Use applicable power unit GVW

(to nearest, higher, 1000 pounds) and the engine rpm (to nearest

100 revolutions) which is required for 60 mph geared speed. For

GVW and engine speed beyond the range of this table, the

following formula shall be used:

FHP = 1 + (0.0000002 rpm) (GVW).
