This does not preclude the free use, in the course of implementing the standard, of necessary details, such as symbols and sizes, type or grade designations. Standards are also reviewed periodically; a standard alongwith amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision. Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions.

The specific and respective values are shown in Annex C. Rims  ISO Rims  ISO For most tyres, the sequence shown accomplishes this objective.
NOTE The measured value includes the bearing and aerodynamic losses of the wheel, the tyre and the drum, losses that are also to be considered. If spindle force is recorded for forward and reverse directions at each test conditioncompensation is achieved by subtracting the “reverse” value from the “forward” value and dividing the result by two. Rims  ISO If dynamic machine calibration is intended, the compensation terms may be easily incorporated in the data reduction.
If this is not available, then the next wider rim may be chosen. You may find similar items within these categories by selecting from the choices below:.

Tyres [1 4] ISO Pneumatic tyres 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO and the following apply. NOTE Historically, the measurement of the fore and aft longitudinal force on a flat surface machine has been shown to be quite difficult since this force is very small relative to other forces being measured- If a flat surface 118164 is used, care should be taken to correlate the data with the reference drum diameter in order to assure accurate results, 5.
