BS EN ISO 25178-602:2025 - TC

This standard BS EN ISO 25178-602:2025 - TC Tracked Changes. Geometrical product specifications (GPS). Surface texture: Areal is classified in these ICS categories:

• 17.040.40 Geometrical Product Specification (GPS)
• 17.040.20 Properties of surfaces

This document specifies the design and metrological characteristics of a particular non-contact instrument for measuring surface texture using a confocal chromatic probe based on axial chromatic aberration of white light. Additional metrological characteristics can be found in ISO 25178-600. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.
