Interlaboratory Rolling Resistance Testing - Highway Truck and Bus Tires 821265
A cooperative round robin test program was initiated among various test facilities in order to validate the procedure specified in the proposed SAE Recommended Practice for the measurement of rolling resistance of highway truck and bus tires. After suitable corrections were made for test drum size and for ambient temperature, the data from all the facilities were found to be clustered about the mean. Where multiple runs were made by a single facility, run to run variability was examined and found to be quite low. It was concluded that consistent rolling resistance data on highway truck and bus tires can be obtained on a variety of indoor test equipment. The conclusions apply if the procedures in the SAE Recommended Practice J1379 and accompanying Information Report J1380 are followed, and suitable correction factors are used.
