ISO 25178 Surface Texture Measurement and Calibration Laboratory Testing Service: A Comprehensive Guide

ISO 25178 is an international standard for surface texture measurement and calibration. It provides a framework for measuring the surface topography of materials, which is essential for ensuring product quality, safety, and performance. The standard is developed by the International Organization for Standardization (ISO) in collaboration with other standard development organizations.

Relevant Standards:

  • ISO 25178:2012(E): Surface texture measurement and characterization Part 1: Measurement of surface topography using stylus method

  • ASTM E18-16: Standard Test Methods for Rockwell Hardness of Metallic Materials

  • EN ISO 4287:1998: Surface texture evaluation; Profiles along straight cuts, measuring length (centre line average roughness, Ra and Rz)

  • TSE EN ISO 4287:2006: Surface texture evaluation; Profiles along straight cuts, measuring length (centre line average roughness, Ra and Rz)

    • Legal and Regulatory Framework:

    The legal and regulatory framework surrounding surface texture measurement and calibration is governed by various national and international standards. These standards ensure that products meet specific requirements for surface texture, which is essential for ensuring product safety, performance, and quality.

    International and National Standards:

  • ISO 25178 is an international standard that provides a framework for measuring surface topography.

  • EN ISO 4287 is a European standard that specifies the measurement of surface roughness using the center line average (CLA) method.

  • ASTM E18-16 is an American standard that specifies the measurement of Rockwell hardness.

    • Standard Development Organizations:

    The International Organization for Standardization (ISO) is responsible for developing and publishing ISO 25178. Other standard development organizations, such as the American Society for Testing and Materials (ASTM), the European Committee for Standardization (CEN), and the Turkish Standards Institution (TSE), also contribute to the development of standards related to surface texture measurement.

    Standard Evolution and Update:

    Standards evolve over time due to advances in technology, changes in industry practices, or new research findings. ISO 25178 has undergone several revisions since its initial publication in 2012.

    Standard Numbers and Scope:

  • ISO 25178-1: Surface texture measurement and characterization Part 1: Measurement of surface topography using stylus method

  • ISO 25178-2: Surface texture measurement and characterization Part 2: Height characterization using focus variation method

    • Industry-Specific Compliance Requirements:

    Various industries require compliance with specific standards for surface texture measurement. For example, the automotive industry requires compliance with ISO 25178-1.
