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.
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.
Measurement decision risk as probability that an incorrect decision will result from a measurement. Are you telling your customers an 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.

Measurement Risk - What you need to know about your calibration provider. You may not be getting what you really need!
Have you ever heard the term measurement risk? It is a real term that may make the difference from a $ 500 loss to hundreds of thousands, or hundreds of millions in losses. When things work, no one really thinks about risk, when they do not, everyone is to blame. This article examines what measurement risk is and why you should care about it.
There’s a question I’ve heard asked more often than it should be: "How should I treat measurement uncertainty contributed by the resolution of a device?"
We guarantee an exceptional customer experience, and will not compromise when it comes to providing you with the best possible calibration service. Discover the benefits of using a results oriented calibration provider by calling Morehouse today.
This document is intended to help properly specify what you may need for ISO/IEC 17025 accredited ASTM E74 calibrations to ensure you are getting exactly what you need
Since I became involved in the calibration industry in 1972, calibration interval has been a common topic of interest and confusion. I was asked to write an article for the newsletter & blog, and after some thought, I determined there was no need. Many people have published excellent content on the subject:
The 3 Key Changes to ISO 9001 Compliance and What this Means for Force and Torque Instrumentation
At Morehouse we strive to replicate the loading conditions a customer may be using. Some other labs, may not follow this process and the additional measurement uncertainty from not replicating use, may create significant error source. Below are the top 5 common force measurement errors that may invalidate the calibration results.
We are writing this post to clear some common ASTM E74 misconceptions. We have written two early blogs on the ASTM E74 standard ASTM E74 Simplified, Calculating CMC using ASTM E74 standard and have a slide share presentation detailing the ASTM E74 standard.
