ISO 19447 specifies the method for measuring the relative ice grip performance index of a candidate tyre compared with a reference tyre under loaded conditions for new tyres intended to be used for passenger cars on surfaces made of ice.
ISO 19447 on Passenger car tyres — passenger car tyres ice grip is useful for:
The method for measuring ice grip performance described in ISO 19447 is meant to reduce the variability of the performance measurement. The use of the proper reference tyres limits the variability of the testing method procedures.
ISO 19447 gives you a method for measuring the relative ice grip performance index of a candidate tyre compared with a reference tyre under loaded conditions for new tyre
