Abstract:

Two people measuring the same product with the same ruler on different days would probably get different results. This could be because of factors such as a change in the room temperature (important for a metal ruler) or different eyesight capabilities. The two measurements might be equivalent or not, depending upon their individual uncertainties. This concept of uncertainty is a measure of the quality of a measurement and can be vital in many cases. The JCGM/100 series of documents establishes general rules for evaluating and expressing uncertainty in measurement that can be followed at various levels of accuracy and in many fields - from the shop floor to fundamental research. Therefore, the principles of these Guides are intended to be applicable to a broad spectrum of measurements, including those required for: * maintaining quality control and quality assurance in production; * complying with and enforcing laws and regulations; * conducting basic research, and applied research and development, in science and engineering; * calibrating standards and instruments and performing tests throughout a national measurement system in order to achieve traceability to national standards; * developing, maintaining, and comparing international and national physical reference standards, including reference materials * other metrology-related aspects.
