BS EN ISO 12179:2026

This standard BS EN ISO 12179:2026 Geometrical product specifications (GPS). Surface texture: Profile. Calibration of contact (stylus) instruments is classified in these ICS categories:

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

This document specifies the calibration and adjustment of the metrological characteristics of contact (stylus) instruments for the measurement of surface texture by the profile method as defined in ISO 25178-601. The calibration and adjustment specified within this document is intended to be carried out with the aid of measurement standards. NOTE            Annex B specifies the calibration and adjustment of metrological characteristics of simplified operator contact (stylus) instruments which do not conform with ISO 25178-601.
