Proving Rings vs. Load Cells — Definitions, Accuracy, and a Practical Comparison. After teaching many classes for NCSLI, ASQ, and other force measurement programs, one question always seems to come up: Which is better—Proving Rings vs. Load Cells? Instead of giving a one-sided answer, the following section takes a closer look at both options. The […]
Which Force Machine Should I Choose? Anyone in metrology has asked—or been asked—this question at some point: “What’s the right force machine for my application?” How do you decide? Word of mouth? A manufacturer’s reputation? Measurement uncertainty? Overall quality? Price? Or some combination of them all? It’s a lot like buying a car. […]
Morehouse Budget Load Cells With accuracies better than 0.02 % of full scale, Morehouse Budget Load Cells are the choice for field measurement capacities 500-112,000 lbf following ASTM E4 and ISO 7500 and for calibration laboratories that want to do more with less budget. Morehouse Budget Load Cells feature the following: ASTM E74 performance: Lower […]
Brinell Hardness Testing Brinell hardness testing is likely the oldest method of hardness testing commonly used today and is used to determine the hardness of castings and forgings with a coarse grain structure. The Brinell test itself is an indentation test where a known indenter, for a Brinell test, is a 10 mm ball applied […]
Rockwell Hardness Testing: Rockwell hardness methods are defined in ISO 6508 & ASTM E18. They are probably the most commonly used method to determine a material’s hardness since it is suitable for almost all metals and, to some extent, plastics. Rockwell test measures the permanent depth of indentation produced by a specified force/load on a […]
Vickers Hardness Testing The Vickers hardness test was developed as an alternative to the Brinell method to measure the hardness of materials. The Vickers hardness test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for […]
Knoop Hardness Testing: The Knoop resulting indentation is not symmetrical as Vickers indentions and is subject to more variations, especially below 200gf. Knoop hardness is not typically being used to define bulk hardness, although at 500 gf standards like ASTM provide conversions of Knoop results to other hardness test scales. Knoop tests are not typically […]
