ASTM F1650 – Standard Practice forEvaluating Tire Traction Performance Data Under Varying TestConditions
1.1”This practice covers the required procedures for examining sequential control tire data for any variation due to changing test conditions. Such variations may influence absolute and also comparative performance of candidate tires, as they are tested over any short or extended time period. The variations addressed in this practice are systematic or bias variations and not random variations. See Appendix X1 for additional details.
1.1.1”Two types of variation may occur: time or test sequence ”’trend variations,”’ either linear or curvilinear, and the less common transient or abrupt shift variations. If any observed variations are declared to be statistically significant, the calculation procedures are given to correct for the influence of these variations. This approach is addressed in Method A.
