ISO 28580: Information on Rolling Resistance (RR)
Document s cited in this standard. The difference between measurement 1 and 2 gives the RR of a tyre. For different Candidate Laboratories, different correlation equations to the Reference Laboratory will exist. Due to the vehicle load, the tyre is deformed in the contact area with the road surface. More information add to ieo.
Different thermal conditioning and the integrated tyre break-in will have only minor impact on RR results. Single point test and correlation of measurement results Status: Candidate Laboratories will purchase alignment tyres. Several parameters are not defined in detail in the current ISO Single point test and correlation of measurement results.
