Truck and bus tyres - Methods of measuring rolling resistance
Applies to all truck and bus pneumatic tyres. 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. Annex A gives test equipment tolerances, annexes B and C (informative) describe optional test conditions and measurement methods of moment of inertia.
