For dated references, only the edition cited applies. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: Pneumatic tyres 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO and the following apply.

Tyre dimensions and load-carrying capacities [1 0] ISO NOTE The measured value includes the drum losses to be considered.

Such a break-in shall be carried out on a test drum of at least 1 ,5 m diameter 1 ,7 m for truck and bus tyres for a period of at least 1 h, at a minimum speed as given in 6.


In measuring tyre rolling resistance, it is necessary to measure small forces in the presence of much larger forces, it is, therefore, essential that equipment and instrumentation of appropriate accuracy be used.

Verfahren zur Messung des Rollwiderstandes. The surface texture shall then be urn deep 80 grit. Depending upon the circumstances of particular tyre applications, it can be useful to determine the effect of these tyre-related parameters for the individual tyre 81164 be tested. The specific and respective values are shown in Annex C. The friction torque, C, of drum bearings can also be measured provided that the rope can be separated from the drum once mass, m, has given sufficient momentum to the drum, for the subsequent drum deceleration is directly related to 1814 by: Worldwide Standards We can source any standard from anywhere in the world.


Rims [1 5] ISO Your basket is empty. Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new iwo when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions.

The choice of an individual method is left to the tester.
