ASME B89.3.4 – Axes of Rotation: Methods for Specifying and Testing
This document is primarily intended for, but not limited to, the standardization of methods of specifying and testing the axes of rotation of spindles used in machine tools and measuring machines. This Standard does not include the subject of angular positioning accuracy. Appendices are attached which provide advisory information for the interpretation and use of…

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…

SAE J911_201704 Surface Texture, Roughness (Ra), Peak Count(Pc), and Mean Profile Spacing, (Rsm) Measurement of Metallic Coated and Uncoated Steel Sheet/Strip to be Formed and/or to be Painted
This SAE Recommended Practice describes a method for measuring roughness average (R\da) and Peak count (PC) of the surface of cold-rolled steel sheet. The method includes a system for equipment configuration, calibration, and procedures for determining average surface roughness, R\da (\gm or \gmin), and average peak count, PC (peaks per cm or peaks per inch)…
