Description (English):

This document specifies generic procedures for the calibration, adjustment and verification of metrological characteristics that areal topography measuring instruments have in common, as stated in ISO 25178-600. Because surface profiles can be extracted from surface topography images, most of the methods described in this document can be adapted to profiling instruments. Instrument-specific issues are not covered by this document. For example, for instruments based on mechanical probing where the probe follows an additional arcuate motion, additional measures are specified in ISO 25178-701. This document does not include procedures for area-integrating methods, although those are also stated in ISO 25178-6. For example, light scattering belongs to a class of techniques known as area-integrating methods for measuring surface topography.

Abstract

Overview

EN ISO 25178-700:2023 - part of the ISO 25178 family - defines generic procedures for the calibration, adjustment and verification of areal topography measuring instruments used in surface texture (areal) metrology. It sets out metrological methods and reporting requirements common to many areal instruments (optical and tactile), and clarifies how to assess instrument performance against the characteristics described in ISO 25178-600. The standard is applicable to areal measurements; many procedures can also be adapted for profiling instruments because profiles can be extracted from areal topography images. Instrument-specific issues (for example, mechanical probes with arcuate motion) and area‑integrating techniques (e.g., light scattering) are outside its scope.

Key topics and technical requirements

Calibration methods and procedures
- Calibration by measurement standards and required measurement procedures.
- Reporting of measurement conditions and handling of defects on material measures.
Metrological characteristics to determine
- Measurement noise and instrument noise (NMI).
- Flatness deviation and associated calibration steps.
- Z-axis amplification coefficient (αz) and z-linearity deviation (lz).
- X/Y amplification coefficients and mapping deviation Δ(x,y).
- Perpendicularity of z-axis relative to x–y reference plane.
- Topographic spatial resolution (instrument transfer function, ITF) and lateral period limit.
- Topography fidelity and small-scale fidelity limits, including slope-dependent effects.
Data quality practices
- Treatment of non-measured points, spurious data and outliers.
- Use of filters/operators and material measures for robust uncertainty estimation.
Documentation
- Mandatory reporting elements for traceability and repeatability.

Practical applications

Establishing and validating calibration procedures in metrology laboratories and calibration service providers.
Setting acceptance criteria and traceable verification workflows for surface metrology in manufacturing quality control (semiconductor, optics, precision engineering).
Evaluating instrument performance for R&D and comparative studies of measuring systems.
Adapting areal calibration procedures when using profilometers by extracting profiles from areal datasets.
