Standard atmospheric conditions for precise measurements have always been priority in metrology. Industrial lengths defined as the size since 1931 have been measured at standard reference temperature of 20°C. As it is practically difficult to maintain this temperature all around the manufacturing or measurement facility at all the time, any change in temperature has to be studied and the resulting change in measurement process has to be accounted. To solve the challenges arising due to this condition, Measurement system analysis (MSA) is used to locate and measure the spread of the variation in measurement system. This paper presents the study conducted on outside micrometer screw gauge at varying room temperature in uncontrolled measuring facility. Bias and Linearity study is performed on the recorded dimensional measurement and temperature data. To study the recorded data, Statistical process control analysis (SPC) is also performed. The study shows the effect of the non-standard temperature over the recorded dimensional measurement data in terms of control charts and bias and linearity values. The paper also discusses real time temperature measurement SCADA system application for the temperature data collection.
