  • ASME B89.3.1-1972 (R2003) Measurement of Out-of-Roundness
    This standard covers the specification and measurement of out-of-roundness of a surface of revolution by the evaluation of a typical cross-sectional profile in terms of its radial deviations from a defined center. While this standard deals primarily with precision spindle instruments for out-of-roundness measurement and polar chart presentation, it is not the intent here to…
