Abstract

The purpose of this study was to assess the uncertainty in measurement of gauge block by micrometer. The study focused on the data collecting from the measurement of gauge block using micrometer in Metrology Laboratory at Fasa B workshop, Universiti Teknikal Malaysia Melaka, UTeM in conjunction to achieve their objectives to find uncertainties and parameters that influence measurement. Uncertainty analysis can be used to provide a meaningful analysis of a massive set of length measurement data. The uncertainty of measurement is a parameter, associated with the result of a measurement, which characterizes the dispersion of the values that could reasonably be attributed to the measurand. The measurands are the particular quantities subject to measurement. A recording data form was constructing to collect the data from the metrology laboratory that consists of parameter data value that used to evaluate the uncertainty in length measurement using micrometer. In this study, it focused on identify the parameter that contributes to the uncertainty in gauge block measurement. The factor that influences the success of any method of evaluating and expressing uncertainty also includes in this study. This thesis also gives a brief explanation about the uncertainty categories that divide into two type which is type A and type B which will describe in next chapter.
