Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...

Abstract: One of basic principle of any organization is to assure about obtained figures from measuring products. If the measured data was not trusted, will be lead to a wrong decisions regarding the approval or rejection of products and obviously the cost would be great. First cases in measurement systems analysis which crossing minds are criteria for approval or rejection any mea...

We frequently do not realize how our decisions depend on the results of a measurement system. We also do not adequately understand the consequences of incorrect results of a measurement system. Imagine that a doctor prescribes medicines to reduce blood pressure (BP) when it is actually normal! Doctors use BP measuring apparatus with mercury column or with a dial type gauge. If the mercury colum...

Due to widely practical application of quality techniques, many decisions in processes and equipment evaluation, control, and improvement are made every day in manufacturing, research, and development. Besides, the philosophy of measurement system analysis (MSA) depends on measurement error which hides true process capability. So it must be implemented prior to any process improvement activitie...

Measurement system analysis (MSA) technique is an important method which is used to analyze statistical discreteness and measurement capability of a measurement system, and also one of quality improvement techniques. The paper describes analysis principle and methods of repeatability and reproducibility (R&R) in MSA, introduces MSA techniques into the field of non-destructive testing (NDT). Bas...

The capability of the dimensions measurement by ten appraisers of ten samples for Charpy Vnotch pendulum impact test was evaluated by Youden plot, analysis of measurement uncertainties, Measurement Systems Analysis (MSA), %P/T, Z-score, Mandel’s statistics and ttest. The group of “better” appraisers given by Youden plot was validated by majority of other methods.

ISO9001:2000 and TS 16949 have become the major quality system management models in present traditional and Hi-tech industries. The Measurement System Analysis (MSA) Reference Manual, on the other hand, is one of the core tools in ISO/TS 16949. MSA aims to evaluate Gauge Repeatability and Reproducibility (GR&R) where the control, monitoring, and maintenance of the measurement process are requir...
