ANSI/ASME B46.1

ANSI/ASME B46.1 is a standard that provides guidelines for measuring surface texture, roughness, and finish of manufactured components. It establishes consistent methods for assessing how smooth or rough a surface is, which can impact performance, wear, and aesthetic appearance. The standard details various parameters, measurement techniques, and tools to ensure accurate and reliable surface evaluations across industries like manufacturing, engineering, and quality control. Essentially, it helps ensure that surfaces meet specific quality and performance criteria through standardized measurement practices.
