| Abstract: |
| Abstract：The testing technologies and principles of tire uniformity and dynamic balance were
introduced，and relevant terms and definitions were explained. China’ s current relevant standards and
specifications for tire uniformity and dynamic balance testing were sorted out. Two metrological technical
specifications of JJF 1839—2020 and JJF 1840—2020 were interpreted in detail from the aspects of
equipment naming，metrological characteristics and calibration conditions，calibration methods and
measurement uncertainty. |
