This is a field traditionally involving scientists from chemistry, physics, biochemistry and other related sciences, but it must be considered also an area of increasing interest to statisticians as well. Skip to main content. Lignes directrices relatives a l’utilisation d’estimations de la repetabilite, de la reproductibilite et de la justesse dans l’evaluation de l’incertitude de mesure. The faster, easier way to work with standards. Often, problems initially associated with processes are found to be due to poorly performing measurement systems.

iso ts 21748 Coordinate measuring machines CMMs are replacing gauges as a tool for process control but there are many issues about how to assess their performance for a particular application and how to design measurement strategies that adequately capture the functionally relevant features of the parts being measured.

Guidance for the use of repeatability, reproducibility and trueness estimates in measurement uncertainty estimation. Accuracy statements or specifications of performance do not always reflect the true influence of the measurement system on the observed process data. Your basket is empty. In recent years, Bayesian approaches to uncertainty evaluation have been implemented, some using Markov iso ts 21748 Monte Carlo simulation. A number of guidelines and standards exist within this area.
A central activity in metrology is the evaluation of uncertainty, a quantitative measure of the quality of a measurement result, enabling measurement results to be compared with iso ts 21748 results, references, specifications or standards.
The SIG has two complementary themes, 1 the application of statistical methods in measurement science metrologyand 2 measurement systems in process control, conformance assessment and quality improvement. The GUM uses the “bottom up” approach deductivei. Find Similar Items This product falls into the following categories.
