BS ISO 15222:2011

Truck and bus tyres. Method for measuring relative wet grip performance. Loaded new tyres. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on commercial vehicles on a wet-paved surface. The methods developed in this International Standard are meant to reduce the variability. The use of a reference tyre is necessary to limit the variability of the testing method procedures. This International Standard applies to all truck and bus tyres (commercial vehicle tyres).
