# BS EN ISO 25178-603:2013: Geometrical product specifications (GPS) - Surface texture: Areal - Part 603: Nominal characteristics of non-contact (confocal chromatic probe) instruments## OverviewBS EN ISO 25178-603:2013 is the British Standard that specifies the nominal characteristics of non-contact (confocal chromatic probe) instruments used for the measurement of surface texture. This standard is part of the ISO 25178 series, which establishes a comprehensive framework for the geometrical specification of product surfaces.The ISO 25178 series covers a wide range of surface texture measurement techniques, including contact, non-contact, and stylus-based methods. Part 603 specifically addresses the use of confocal chromatic probe instruments, which are a type of non-contact optical profiling system.## Key Benefits- Ensures consistent, reliable, and accurate surface texture measurements across industries- Enables compliance with international standards for product quality and metrology- Provides a common language and framework for specifying and communicating surface texture requirements- Supports the development of advanced manufacturing techniques and quality control processes## Technical Specifications- Scope: Specifies the nominal characteristics of non-contact (confocal chromatic probe) instruments used for the measurement of surface texture in accordance with the ISO 25178 series- Applicable Instruments: Confocal chromatic probe instruments, which use the principle of chromatic aberration to measure surface height- Measurement Principles: Confocal chromatic probe instruments operate by focusing a polychromatic light beam onto the surface and detecting the wavelength of the reflected light, which is related to the surface height- Measurement Characteristics: - Lateral resolution - Vertical resolution - Measurement range - Measurement speed - Measurement uncertainty- Calibration and Traceability: Provides guidance on the calibration and traceability of confocal chromatic probe instruments to ensure measurement accuracy and reliability## Compliance and ApplicationsBS EN ISO 25178-603:2013 is an essential standard for industries that require precise and reliable surface texture measurement, such as:- Automotive manufacturing- Aerospace engineering- Medical device production- Precision engineering- Semiconductor fabrication- Additive manufacturingBy adhering to the specifications outlined in this standard, manufacturers and quality control professionals can ensure that their surface texture measurements are consistent, traceable, and compliant with international standards. This, in turn, supports the development of high-quality products, the optimization of manufacturing processes, and the advancement of cutting-edge technologies.Whether you're working in a laboratory, a production facility, or a research and development environment, BS EN ISO 25178-603:2013 is a critical reference for ensuring the accuracy and reliability of your surface texture measurements.
