What is EN ISO 1168:2016?

EN ISO 1168:2016 is a professional technical standard that provides guidelines for the measurement of surface roughness parameters. It defines terms related to surface texture and specifies the procedure for assessing surface roughness through profilometric methods. This standard aims to ensure consistency in measuring surface roughness across different industries and applications.

Importance of Measuring Surface Roughness

Surface roughness is an important characteristic of many materials and surfaces. It affects various aspects such as functionality, performance, and aesthetics. Understanding and measuring surface roughness is crucial in industries like manufacturing, automotive, aerospace, and medical, where precision and quality are paramount. By adhering to EN ISO 1168:2016, professionals can accurately evaluate and compare surface roughness measurements, enabling them to make informed decisions regarding material selection, process optimization, and product performance.

Profilometric Methods for Surface Roughness Measurement

EN ISO 1168:2016 specifies profilometric methods for measuring surface roughness. Profilometry utilizes astylus or optical probe to scan across a surface, recording the vertical deviations in height. These measurements are then used to calculate various surface roughness parameters, including Ra (average roughness), Rz (mean peak-to-valley height), Rp (maximum profile peak height), and many more. The standard provides guidelines on instrument calibration, measurement procedures, data analysis, and reporting requirements to ensure accuracy and repeatability of results across different measurement systems.

Benefits and Applications

Applying EN ISO 1168:2016 offers several benefits. Firstly, it establishes a common language for discussing and specifying surface roughness parameters, facilitating effective communication between engineers, manufacturers, and suppliers. Secondly, it promotes consistency in measurement practices, allowing for accurate comparisons and evaluations of surface texture. Thirdly, it enhances product quality by enabling manufacturers to meet specific roughness requirements, particularly in industries where precise functionality or aesthetic appearance is critical. By adhering to this standard, companies can achieve operational excellence, improve customer satisfaction, and gain a competitive advantage over their peers.
