Full title and description

Geometrical product specifications (GPS) — Surface texture: Areal — Part 6: Classification of methods for measuring surface texture. This part of ISO 25178 defines a classification system for methods used primarily to measure areal surface texture (surface topography), describes three main classes of measurement methods, illustrates relationships between classes and provides brief descriptions of specific methods to support selection and understanding of measurement techniques.

Abstract

ISO 25178-6:2010 establishes a general, method‑centric classification for instruments and measurement procedures used to capture surface topography on an areal basis. The standard is intended to provide context for other parts of the ISO 25178 series that specify parameters, operators and metrological/nominal characteristics for particular measurement technologies.

Scope

ISO 25178-6:2010 specifies a classification system for methods used primarily to measure surface texture (areal). It defines three classes of measurement methods, shows how those classes relate, and briefly characterises specific methods. The scope is intentionally general to provide a framework for developing other parts of the ISO 25178 series that define parameters, calibration/nominal characteristics and method‑specific requirements; the standard also recognises that some instruments may not fit unambiguously into a single class.

Key topics and requirements

• Classification framework for areal surface texture measurement methods (three primary classes).
• Definitions and relationships between class types to aid selection and comparison of methods.
• Brief descriptions of representative measurement techniques (contact and non‑contact approaches).
• Context for the development and application of other ISO 25178 parts (parameters, operators, instrument characteristics).
• Guidance that the classification is general and that some instruments may span classes or be difficult to categorise.

Typical use and users

Used by metrology laboratories, instrument manufacturers, quality engineers, research groups, and standards committees to classify measurement methods, identify applicable complementary standards, and guide procurement, calibration and test-method selection for areal surface texture measurement.

Related standards

ISO 25178-6 is part of the ISO 25178 series on areal surface texture (GPS). Related parts include: Part 1 (indication of surface texture), Part 2 (terms, definitions and parameters), Part 3 (specification operators), Part 70/71/72 (material measures, software measurements, x3p file format) and several later parts addressing metrological and nominal characteristics of specific contact and non‑contact instruments. The part functions as the method‑classification backbone for these documents.

FAQ

Q: What is this standard?

A: ISO 25178-6:2010 is the part of the ISO 25178 series that defines a classification system for methods used to measure areal surface texture (surface topography).

Q: What does it cover?

A: It covers a general classification of measurement methods (three classes), illustrates relationships between classes, and briefly describes representative methods to provide a framework for other parts of ISO 25178 that specify parameters and instrument characteristics.

Q: Who typically uses it?

A: Metrology laboratories, instrument manufacturers, QA/quality engineers, researchers in surface metrology, and standards committees use it to classify methods and to determine which complementary standards apply to a given measurement technique.

Q: Is it current or superseded?

A: ISO 25178-6:2010 is published and was reviewed/confirmed in 2020. A revision (Draft International Standard ISO/DIS 25178-6) is under development to replace the 2010 edition; users should check the current ISO work status if they need the very latest revision information.

Q: Is it part of a series?

A: Yes — it is Part 6 of the ISO 25178 series on areal surface texture (Geometrical Product Specifications — Surface texture: areal) and is intended to work together with Parts 1, 2, 3, 70–72 and additional parts addressing instrument characteristics and metrological requirements.

Q: What are the key keywords?
