Abstract

Conformity assessment is a process commonly used in calibration activities to ensure the validity of the results of measurements or calibrations with specific requirements or standards. In this research the use of conformity assessment was carried out on long gauge block calibration activities in National Metrology Institute of Indonesia by determining objective criteria called decision rule which aims to determine the limit of conformity assessment, conformance zone, and specification zone requested by the calibration customer. Decision rules are made by referred in statistical acceptance sampling based on go/no-go decisions with Gaussian Probability Density Function for the measured quantity. From this research, it was found that in the calibration process of long gauge block, the use of the decision rule concept was to use tolerance interval with a guard band. The guard band value is obtained from the uncertainty measurement analysis of the long gauge block calibration, while the acceptance zone value is obtained from the limit deviation of long gauge block based on ISO 3650.
