MICROHARDNESS TESTING OF PLATED COATINGS: DEFINING PRECISION AND BIAS FOR ASTM B578 by

نویسنده

  • Jack Horner
چکیده

Since 1980, ASTM has required that test methods include statements on the precision and bias of each method. E384 and B578, each committee responsible for these documents, E04 and B08, initiated new interlaboratory comparison studies, commonly referred to as round-robins. These studies involve circulating standard materials to each of several chosen laboratories for measurements. Considerable and attention to detail are required (1)(2). ASTM Committee EO To develop these missing parts of

Realistic Evaluation of the Precision and Accuracy of Instrument Calibration Systems

Prior to the publication of Realistic Evaluation of the Precision and Accuracy of Instrument Calibration Systems by Churchill Eisenhart [1], the terms “precision” and “accuracy” were used in a qualitative manner to characterize measurements. These terms appeared in many American Society for Testing Materials (ASTM) standards long before any common agreement or understanding had been reached as ...

Precision and Reliability Incensement of Inertial Navigation System with Rotation and Redundancy

Precision and reliability are two main performance characteristic in low-cost Inertial Navigation System(INS). Increase of precision in low-cost INS without auxiliary sensors is main challenge. Bias instability leads to position drift error in inertial navigation system. In addition, fault occurrence makes the sensor reliability is decreased. Rotation of Inertial Measurement Unit(RIMU) and use ...
