The following bibliographic material is provided to assist you with your purchasing decision:

This International Standard specifies test methods for determining the characteristic longitudinal friction force values of paved surfaces using either a standard reference test tyre or the tyre of a vehicle under test. General test procedures and their validity are presented for determining peak- and slide-braking coefficients on actual test surfaces, where the surface conditions are determined and controlled by the user at the time of testing. Test and test-surface condition documentation procedures and details are also specified. The purpose of this International Standard is to provide for the harmonization of results of testing on different test tracks. The values measured with standard reference test tyres (SRTT) are intended to form standard reference numbers indicating the friction properties of test tracks and road surfaces that are representative for passenger car tyres. Certain of the methods may also be suitable for measuring the friction properties for a specific test car tyre on the test track. The values quantify the peak-, near-peak or slide-braking coefficients at the time of test and do not necessarily represent fixed values. The values measured with reference tyres are intended as reference numbers indicating certain friction properties of test tracks and road surfaces. This International Standard does not purport to address all the safety problems associated with its use. It is the responsibility of the user to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
