What is measurement risk?

April 12, 2017

Measurement decision risk as probability that an incorrect decision will result from a measurement. Are you telling your customers instrument passes without considering measurement uncertainty? If taken to court, are your measurement defensible? This paper examines the proper way to make statements of compliance.

Uncertainty propagation for force calibration systems, or how to put together a force CMC.

February 07, 2017

Having troubles understanding measurement uncertainty and how to put together a budget? This paper examines all of the components required to put together a full calibration and measurement capability (CMC) reviewed by Accreditation Bodies for your scope. This is a guide to calculating force measurement uncertainties and was published in Cal Lab magazine.

The Design, Development and Commissioning of a 2kNm Torque Standard Machine

January 02, 2017

This paper describes NPL’s 2 kN·m torque machine — Now at Morehouse Instrument Company — a lever deadweight machine with a vertical torque axis and an uncertainty of ±0.002 %. Despite the greater difficulty in applying torques to a vertically mounted transducer, this design was selected as it enables a symmetric “pure” torque to be applied. In addition, this design provides adaptability, enabling comparisons with the application of asymmetric torque and “on-thefly” torque calibrations to be studied.

The Top 5 costly calibration mistakes for force measurements

September 01, 2017 12:00:00

Not choosing a calibration provider who follows published standards, calculates risk properly, and has open communication with customers about the importance of calibrating the instrument, in the same manner, it is used is critical to lessening measurement risk and ensuring the repeatable results. If these steps are not followed OOT (Out Of tolerance) situations are very probably and these are never cheap. Thus we wrote the top 5 costly calibration mistakes for force measurements.

How do you know if your device is “In-Tolerance”? Why the location of the measurement is more important than you may realize.

June 23, 2017 12:00:00

Calling an instrument “In Tolerance” is about location, location, location. It’s also about the uncertainty of the measurement, but a bad location is going to raise the Probability of False Accept (PFA) significantly. The probability of false accept is the likelihood of a lab calling a measurement “In Tolerance” when it is not. This post deals with exposing some bad practices labs make by calling equipment good when it is not.
