This International Standard specifies test methods for determining the characteristic longitudinal friction force<\/p>\n
values of paved surfaces using either a standard reference test tyre or the tyre of a vehicle under test. General test<\/p>\n
procedures and their validity are presented for determining peak- and slide-braking coefficients on actual test<\/p>\n
surfaces, where the surface conditions are determined and controlled by the user at the time of testing. Test and<\/p>\n
test-surface condition documentation procedures and details are also specified.<\/p>\n
The purpose of this International Standard is to provide for the harmonization of results of testing on different test<\/p>\n
tracks. The values measured with standard reference test tyres (SRTT) are intended to form standard reference<\/p>\n
numbers indicating the friction properties of test tracks and road surfaces that are representative for passenger car<\/p>\n
tyres.<\/p>\n
Certain of the methods may also be suitable for measuring the friction properties for a specific test car tyre on the<\/p>\n
test track.<\/p>\n
The values quantify the peak-, near-peak or slide-braking coefficients at the time of test and do not necessarily<\/p>\n
represent fixed values.<\/p>\n
The values measured with reference tyres are intended as reference numbers indicating certain friction properties<\/p>\n
of test tracks and road surfaces.<\/p>\n
This International Standard does not purport to address all the safety problems associated with its use. It is the<\/p>\n
responsibility of the user to consult and establish appropriate safety and health practices and determine the<\/p>\n
applicability of regulatory limitations prior to use.<\/p>\n
NOTE 1 Friction is affected by many variables such as environmental conditions, usage, age and surface contamination.<\/p>\n
Measured values will change when any of these conditions significantly changes.<\/p>\n
NOTE 2 The measured braking coefficient values obtained with the procedures stated in this International Standard may not<\/p>\n
necessarily agree or correlate directly with those obtained by other surface coefficient measuring methods.<\/p>\n","protected":false},"excerpt":{"rendered":"
