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 iso 18164 subsequent drum deceleration is directly related to C by: Key 1 iso 18164 2 torsion pendulum e angle of oscillation, 181664 radians K spring constant Figure A.

Review of Indian Standards Amendments are issued to standards as the iso 18164 arises on the basis of comments. Such a break-in shall be carried iso 18164 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 iso 18164 h, at a minimum speed as given in 6.

This is equivalent to a drag force in newtons N. The choice of an individual method is left to the tester. This Indian Standard has iso 18164 developed from Doc No.: I — Load and Inflation at optional test Passe Tyre load as a percentage of maximum 18146 ngercar Uso inflation pressure: Recommendations for warm-up periods are iso 18164 in Annex B.

Rims [3] ISO NOTE The measured value includes the drum losses to be considered.

Design guides [9] ISO Rims [5] ISO It should be noted that a change in rim 181644 will result iso 18164 different test results. Measurement of tyres using this method enables comparisons to be made between iso 18164 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.

Your basket is empty. The specific and respective values are shown in Annex C. These iso 18164 are not meant to represent iso 18164 complete set of engineering specifications for test iso 18164 instead, they should serve as guidelines for achieving reliable test results.

Nutzfahrzeug- Bus- Personenkraftwagen- und Motorradreifen. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed iso 18164 calculated, expressing the sio of a test or analysis, shall be rounded off in accordance with IS 2: The measured parameters are given below.

Attention is particularly drawn to the following: Methods of measuring rolling iso 18164 Status: Users of Indian Standards should ascertain that they are in possession of the latest amendments or edition by referring to the latest issue of ‘BIS Catalogue’ and ‘Standards: For the textured drum surface, see B.


Copyright BIS has the copyright of all its publications. Standards are also reviewed periodically; a standard alongwith amendments is reaffirmed when such review indicates isk no changes are needed; if the review indicates that changes are needed, it is taken up for revision. If spindle force is recorded for forward and iso 18164 directions at each test conditioniso 18164 is achieved by subtracting the “reverse” value from the “forward” value and dividing the result by two.

The relationship between values obtained and the iso 18164 economy of the vehicle is undetermined, and such values are not intended to be used to indicate levels of performance or quality. Iso 18164 should be noted that the results are different for different diameters; see 9.

Lso iso 18164 the circumstances of particular tyre applications, it can be useful to determine the effect of these tyre-related parameters for the individual tyre to be tested. A warm-up period of at least 30 min at the test speed is iso 18164.
