What is BS ISO 4287:1997?

BS ISO 4287:1997 is an internationally recognized technical standard that provides guidelines for specifying and testing surface texture of solid materials. It defines terms related to surface texture, establishes methods for its measurement, and outlines procedures for presenting measurement results.

Importance of Surface Texture Measurement

Surface texture plays a crucial role in various industries, including manufacturing, engineering, and design. It affects the functionality, performance, and quality of products. Accurate and consistent measurement of surface texture is essential for ensuring compliance with specifications, evaluating product performance, and providing meaningful data for research and development purposes.

Methods for Surface Texture Measurement

BS ISO 4287:1997 outlines different methods for measuring surface texture. These methods include contact and non-contact techniques, each suitable for specific applications. Contact stylus instruments typically involve scanning a surface with a diamond-tipped stylus to measure parameters such as roughness, waviness, and profile. Non-contact methods, such as optical or laser-based instruments, use light or laser beams to capture surface data without physically touching the material.

Presentation of Surface Texture Data

The standard also provides guidelines on how to present surface texture measurement results. This includes conventions for expressing parameters, such as Ra (arithmetical mean roughness), Rz (ten-point height), and Rmr (material ratio). Consistent presentation ensures clarity and facilitates comparison and analysis of data across different platforms and industries.
