In product quality control, quality management systems (DIN ISO 9000 to 9004) play a decisive role in industrial production. Surface roughness and other measurements are required in many industrial fields. However, any high-precision equipment measurement will have small deviations. Regular calibration can control these deviations (such as depth, waviness, surface roughness, etc.) within the standard range. , In order to minimize the uncertainty of the measurement equipment for parameters such as the roughness or depth of the sample structure and maintain the high precision of the equipment, the internationally certified calibration standard must be used for metrological calibration. According to the current regulations, the calibration standard must be Certified by the German PTB or other international authorities and accompanied by a certification certificate.
