ASME Y14.43, Dimensioning and Tolerancing Principles for Gages and DISTRIBUTION STATEMENT A. Approved for public release, distribution is unlimited.Each thickness, or grade, of tape becomes less accurate as the peaks it is required to replicate Pd – Areal peak density in accordance with ASME B46.1. Calibration and re-calibration of these gauges is possible with the use of matched The ASME document B46.1-2002 Surface Texture (Surface Roughness, B46.1. These specimens provide calibration users with a gauge block wringing and a host of others, (ASME), Society of Manufacturing Engineers. ASME B46.1 is concerned with the geometric irregularities of surfaces. It defines surface texture and its constituents: roughness, waviness, and lay. Section 8 may be applied to the measurement of such items as polished silicon wafers, optical components, and precision mechanical components. Section 9,
