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

Measurement Risk

Device Resolution and the Impact on Consumer Risk 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 test protocols […]

Specifying a Tolerance, the Difference Between Percentage of Indicated Value vs % of Full-Scale Output

Measurement Risk

In looking at various equipment, it seems the force equipment in the test and measurement industry specifically has mainly specified tolerances as a percent of full scale. Several crane scales, tension links, hand-held force gauges follow this trend when determining accuracy or tolerance. There are a few manufacturers who use % Indicated Value (IV). My […]

Why a 4:1 TUR is not enough: The importance of analyzing the probability of false accept risk

Measurement Risk

Figure 1 Graph Showing Method 5 Acceptance Limits Several organizations and publications reference or insist on maintaining a 4:1 Test Uncertainty Ratio (TUR) without understanding the level of risk that they may be subjecting themselves to. The general thought is as long as the lab performing the calibrations has standards at least four times better […]

What happens when you overshoot a test point?

Measurement Risk

What happens when you overshoot a test point? Various calibration laboratories are using hydraulic, screw, and other force calibration machines where it is difficult not to overshoot a test point. By talking about overshooting a test point we are referring to loading past the desired point and then letting the creep in the hydraulic system naturally […]

The Top 5 costly force measurement mistakes

Measurement Risk

The Top 5 costly force measurement mistakes #1 of 5 Costly force measurement mistakes Most calibration laboratories will say a device is "In Tolerance" without considering the uncertainty of their measurement process. This equates to you not using a calibration laboratory that has standards to meet your needs and accounts for measurement risk properly. Most […]

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

Measurement Risk

How do you know if your device is “In-Tolerance”? Why the location of the measurement is more important than you may realize. Calling an instrument “In Tolerance” is about the location, location, and location of the measurement. It’s also about the uncertainty of the measurement, but a bad location is going to raise the Probability […]

Making a statement of compliance: The 3 main reasons calibration laboratories fail to get things right

Measurement Risk

Making a statement of compliance 3 must-haves Metrological Traceability, Measurement Uncertainty, and Measurement Risk Making a statement of compliance introduction. About a year after turning 40, I bought a pair of reading glasses. After another year, I started noticing a decrease in my overall vision and figured I needed to visit an eye doctor. I […]
