QC/T 717-2015 Translated English of Chinese Standard. (QCT 717-2015, QC/T717-2015, QCT717-2015): Road vehicles - Wheels - Requirements and measuring methods of radial and lateral run-outhttps://www.chinesestandard.net, 20 avr. 2014 - 18 pages This standard defines parameters that characterize the geometric uniformity of the wheel and describes the principles of measurement of these parameters. This standard specifies the requirements for the peak-to-peak value of the radial runout, the peak-to-peak value of the lateral runout, the first harmonic of the average of radial runout, the first harmonic of the average of lateral runout of the vehicle wheel. |
