Automotive Engineering Road Test Protocols

The following are gleaned from the aforementioned literature:
1) Pre-testing requires approximately 30-miles @ 50-mph,thermal ambient condition equilibrium stabilization for:
* Tire temperature-related R-R variability
* Temperature / viscosity - related hydrodynamic tribological mpg- variability to guaranty repeatability.
--------------------------------------------------------------------------------------
2) constant grade test course ( coast-up / coast-down ) prevention
3) wind less than 15-km/h ( 9.3- mph )
4) peak wind speed less than 20-km/h ( 12.4-mph )
5) continuous data-logging of :
- ambient temperature
- barometric pressure
- relative humidity
- road temperature
6) Reid Vapor Pressure ( RVP ) of fuel
7) Distillation temperature of fuel
8) No accessories allowed ( HVAC or Blower fan ) [alternator loading]
9) Recommended 68-F through 86-F ambient temperature window
10) 1/10th-gallon, graduated Burette fuel supply
11) Fuel mass, thermal - expansion compensation factoring
12) Instantaneous fuel rate by mass
13) Ambient, environmental, axial and crosswind aerodynamic loading
14) Uniform pavement surface
15) Straight course
16) Dry course
