Coupling (hitch) height definition
Coupling (hitch) height means the height when measured perpendicularly from the centre of the articulation point of the trailer towing coupling or hitch to the ground, when the towing vehicle and trailer are coupled together. The vehicle and trailer shall be standing on level pavement surface in its test mode complete with the appropriate tyre(s) to be used in the particular test.

Rolling resistance measurement - Specific definitions 3.18.1. Rolling resistance FrLoss of energy (or energy consumed) per unit of distance travelled. 3.18.2. Rolling resistance coefficient CrRatio of the rolling resistance to the load on the tyre. 3.18.3. New test tyreA tyre which has not been previously used in a rolling deflected test that raises its temperature above that generated in rolling resistance tests, and which has not previously been exposed to a temperature above 40 °C. , 3.18.4. Laboratory control tyreTyre used by an individual laboratory to control machine behaviour as a function of time. 3.18.5. Capped inflationProcess of inflating the tyre and allowing the inflation pressure to build up, as the tyre is warmed up while running. 3.18.6. Parasitic lossLoss of energy (or energy consumed) per unit distance excluding internal tyre losses, attributable to aerodynamic loss of the different rotating elements of the test equipment, bearing friction and other sources of systematic loss which may be inherent in the measurement. 3.18.7. Skim test readingType of parasitic loss measurement, in which the tyre is kept rolling without slippage, while reducing the tyre load to a level at which energy loss within the tyre itself is virtually zero. 3.18.8. Inertia or moment of inertia.Ratio of the torque applied to a rotating body to the rotational acceleration of this body. 3.18.9. Measurement reproducibility σmCapability of a machine to measure rolling resistance. 4.0 Markings 4.1 All tyres constituting the type of tyre shall be marked as prescribed by either Standard IS 15633 or IS 15636, as applicable. 4.2 In particular tyres shall bear 4.2.1 The manufacturer's name or trade mark; 4.2.2 The trade description (see paragraph 3.2. of this Standard). However, the trade description is not required when it coincides with the trade mark;
