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 iso 18164 at least 1 h, at a minimum speed as given in 6. The relationship between values obtained and the fuel economy of the vehicle is undetermined, and such values are not intended to be used to indicate levels of performance or quality.

The faster, easier way to work with standards. Rims [8] ISO 1816 does not preclude iso 18164 free use, in the course of implementing the standard, of iso 18164 details, such as symbols and sizes, type or grade designations. A warm-up period of at least iso 18164 min at the test speed is required.

This is equivalent to a drag force in newtons N. Copyright BIS has the copyright of all its publications. A warm-up period of at least 30 min for the first speed and iso 18164 least 20 min for each successive speed is required. Unless otherwise noted, all aspects of the standard test conditions apply.

NOTE The iso 18164 value includes the bearing and aerodynamic losses of the wheel, the tyre and the drum, losses that are also to be considered.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, iso 18164 or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: Search all products by.

Jhe number of significant places retained in the rounded off value should be the same iso 18164 that of the specified value in this standard.

This Indian Iso 18164 has been developed from Doc No.: Rims [3] ISO This measured value also includes the bearing losses of the tyre spindle and the aerodynamic losses of the isso and the wheel.

Attention is particularly drawn to the following: Certain conventions are, however, not identical to those used in Indian Standards. This International Standard applies to ail passenger car, truck, bus and motorcycle tyres. 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 iso 18164 to other forces being measured- If a flat surface machine is used, care should be taken to correlate the iso 18164 with the reference drum diameter iso 18164 order to assure accurate results, iso 18164.

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. A warm-up period of at least 90 min for capped pressure conditions iso 18164 at least 30 min for regulated pressure conditions is required. Tyres [1 4] ISO NOTE Annex A gives guidelines and practical examples to measure the moments of inertia for the deceleration method.
