This test method has better repeatability and reproducibility than manual method D97. Both repeatability and reproducibility are usually reported as a standard deviation. Its biggest advantages are repeatability and reproducibility once it is properly configured. The standard deviation under repeatability conditions is part of precision and accuracy. However, this measurement technique results in high accuracy and high repeatability. Laser cutters have positioning accuracy of 10 micrometers and repeatability of 5 micrometers. Such devices may provide improved repeatability, accuracy and precision over a mechanical switch. This eliminates turbulence found in gravity casting and increases density, repeatability, tolerances, and grain uniformity. ISO 9283 sets out a method whereby both accuracy and repeatability can be measured. A pneumatic torque wrench has very little vibration, and excellent repeatability and accuracy. Reliability measures the consistency or repeatability of an observation. Water jets are capable of attaining accuracy down to and repeatability down to . These transducers have low hysteresis and excellent repeatability. However, the fine the scale comes with cost of repeatability therefore reliability. Key distinctions between process management and project management are repeatability and predictability.
