Gage Repeatability and Reliability: Ensuring Accurate Test Results for Measurement Systems
One of the questions our applications team is most commonly asked is “Why aren’t my systems producing the exact same results?” Over years of applications consulting, we have found that optimizing the test configuration by instructing labs to use the same method files, implement standard operating procedures (SOPs) and use equivalent test setups is the best way to minimize test result differences. However, application engineers can only do so much as differences do exist in the real world. For example, every mechanical testing system is different, laboratories have different operators using their systems, different samples are actually being tested, and each specimen being tested is prepared with slight differences. There are many sources and reasons that may cause these differences and the sum of the differences may produce an overall error in the test results.
