Making Better Measurement Decisions: Understanding Risk in Simple Terms

Understanding Risk: Making Better Measurement Decisions   Understanding Risk Intro:   Why Measurements Aren’t Always Exact Every measurement we take comes with some level of doubt. This doubt is called measurement uncertainty. It’s the range within which the “true value” probably lies. When understanding risk, think of it like reading a ruler: if your eyes […]

Start With the End in Mind: Working Backwards to Size Your Measurement Equipment and Calibration Provider

Start With the End in Mind: Working Backwards to Size Your Measurement Equipment and Calibration Provider A practical, risk-informed method for selecting equipment, decision rules, and calibration providers   Abstract Begin with the decision you must defend—product conformance with acceptable risk—and work backwards to derive the measurement capability required of both your equipment and your […]

Force Calibration Simplified: Expected Performance in Load Cell Calibration Procedures

Force Calibration Simplified: Expected Performance in Load Cell Calibration Procedures Expected performance in load cell calibration procedures is a key concept that we have adopted at Morehouse. The term likely originated from discussions during ASTM committee meetings among industry experts. Expected performance helps define how accurately a force-measuring tool works when tested under ideal laboratory […]

6 Exciting Things Everyone Should Know About NIST Traceable Force Measurements

6 Things Everyone Should Know About NIST Traceable Force Measurements   Many organizations with people in them still use outdated terminology. Such terminology uses the term NIST traceable force measurements or requests that calibration be NIST traceable. In measurement standards, the term "traceability" often invokes thoughts of the National Institute of Standards and Technology (NIST), […]

Guarded Rejection: 1 Valuable Tool for Reducing the Risk of False Rejection

Guarded rejection: 1 Valuable Tool for Reducing the Risk of False Rejection  When assessing the conformity of a product or service to a specified requirement, it is crucial to have a high degree of confidence in the decision. This is especially true when the consequences of a false rejection or false acceptance are high. Guarded […]

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 […]
