*          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.  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 SAE Work Sheet Item 1 should include the vehicle model number, wheelbase engine model number, and vehicle type.  The factors to be used in predicting truck ability (site 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 tire furnished by the contractor in accordance with this specification.

Table 2               -  Altitude Factor.  1.00

Table 3               -  Rolling Factor.  2.080

Table 4               -  Area Factor.  0.092

Table 5               -  Velocity Factor.  432.0

Table 6               -  Altitude Factor.  1.00

Table 7               -  Chassis Friction Horsepower.  4.5

Table 8               -  Grade Factor.  0.62

Table 8A            -  Correction Factor.  Not required

Table 9               -  Road Factor.  0.0.

6.4  Oxygen tank.  The following are the appropriate dimensions, weights, and capacities of the various sizes of oxygen cylinders referenced in this specification (Tanks shall conform to DOT specification 3AA2015):

"E"                  "M"

6.5  International Standardization Agreement.  Certain provisions of this specification pertaining to litter handling capability (see 3.6.1, table II, 3.6.3, and figure 1) are the subject of international standardization agreement, STANAG No. 2040.  When an amendment, revision, or cancellation of this specification is proposed which will affect or violate the international agreement concerned, the preparing activity will take appropriate reconciliatory action through international standardization channels including departmental standardization office, if required.
