{"id":"gauge-r-and-r","model_id":"Gauge R&R","name":"Gauge R&R","summary":"Gauge R&R is a study used to characterize the performance of gauges and instruments in production by examining errors that affect measurements. The study covers design considerations, data collection, measurement variability, bias analysis, remedies and strategies, and quantification of measurement uncertainties.","study_notes":["Study design considers artifacts, operators, gauges, parameter levels, and configurations.","Data collection is a defined part of the study.","Measurement variability is quantified through repeatability, reproducibility, and stability.","Bias analysis includes resolution, linearity, hysteresis, drift, differences among gauges, and differences among geometries or configurations.","The document also addresses remedies and strategies and quantifying uncertainties of measurements made with gauges."],"safety_notes":[],"sources":[{"url":"https://www.itl.nist.gov/div898/handbook/mpc/section4/mpc4.htm","title":"2.4.
