A Simplified Global and Specific Risk Example

A Simplified Global and Specific Risk Example A company has hired us to measure the speed of cars on a stretch of a single-lane road. The customer wants options using both Global and Specific Risk examples as they are unsure what method will give them what they need to meet the specification as they know […]

Understanding Global Risk in 8 Steps Using Simple Terms

Understanding Global Risk in Simple Terms In the world of engineering and product design, there's a concept that Henry Petroski discusses in his book, "To Engineer is Human: The Role of Failure in Successful Design." He suggests that engineers and companies might become complacent when things are going well. They might not take the necessary […]

Delving into Specific Risk: A Comprehensive Understanding of PFA and PFR

Delving into Specific Risk: A Comprehensive Understanding of PFA and PFR Specific risk in metrology, mainly focusing on the Probability of False Acceptance (PFA) and Probability of False Rejection (PFR). These concepts are crucial in the decision-making process based on measurement results. Specific Risk  Specific risk, as the term suggests, is a risk that is […]

A Simplification of the Differences Between Specific and Global Risk

A Simplification of the Differences Between Specific and Global Risk Understanding the Differences Between Specific and Global Risk is a complex topic. For this article, we are going to explain the difference between specific and global risk without getting into too much detail. In metrology, risk is a crucial factor influencing the decision-making process based […]

Decision Rules - Our Top 10 Recommended Reading List

Decision Rules - Our Top 10 Recommended Reading  Many people struggle with decision rules and implementing decision rules. At Morehouse, we have been privileged to be part of the Metrology Handbook 3rd Edition, where we helped write a chapter on decision rules. Though it was an honor to write that and other chapters, there are […]

The Amazing Morehouse MURA Metrology Chatbot

Morehouse MURA Metrology Chatbot Morehouse has launched our Metrology Chatbot. The bot is found on our website and is active on every page. The major advantage of our MURA (Measurement Uncertainty Resource Assistant) is it is trained using all of the material from our website and more. See our official press release here. This might […]

Let's Talk about Bias: The Force Measurement Error Kind!

Let's Talk about Bias: The Force Measurement Error Kind! What can happen when we use an accuracy specification and assume all the measurements are centered in relation to the specification limits? It is a typical problem in the metrology community, where many papers assume a centered process or Measurement. When the Measurement deviates from the […]

Must Know Information on How to Calculate TUR?

How Do I Calculate TUR? How to Calculate TUR. Correctly calculating Test Uncertainty Ratio (TUR) is crucial because it is a commonly accepted practice when making a statement of conformity. It helps you analyze measurement risk and is often used in decision rules. Although TUR is defined in the ANSI/NCSL Z540.3 Handbook and ILAC G8, […]

The New Dimension to Resolution: Can it be Resolved?

The New Dimension to Resolution: Can it be Resolved? Our last blog, Device Resolution and the Impact on Consumer Risk, described why best practices should be followed for conformity assessments rather than drafting individual test protocols and standards. How should manufacturers and calibration laboratories correctly calculate both uncertainty and risk on equipment? Risk, Conformity Assessment, […]

Device Resolution and the Impact on Consumer Risk

Device Resolution and the Impact on Consumer Risk - Intro If a device's uncertainty has too coarse of a resolution, then you need a device that does not subject the conformance decision to higher risk. This blog will present examples that demonstrate why best practices should be followed for conformity assessments rather than drafting individual […]

TAR versus TUR: Why TAR should RIP ASAP

TAR versus TUR: Why TAR should RIP ASAP In our last blog, Examining the History of TAR and TUR, we looked at several outdated, and to some extent wrong, practices such as Test Accuracy Ratio (TARs) and requesting NIST traceable calibrations. Remember when they buried the word "DEF"? Maybe we, as metrologists, need to do […]

Examining the History of TAR and TUR

Examining the History of TAR and TUR Why examine TAR and TUR? Hasn’t each topic been covered for decades now? When we look at TAR and TUR concepts, we find that many in the metrology community have adopted TUR. Both guidance documents and standards have moved away from TAR. However, when we look at the […]
