According to ASTM E2554 we can use control chart to determine uncertainty of a test (ASTM tests). The standard deviation is the uncertainty for that particular test. A2LA has the same guide. Control charting seems a simple and straightforward way to determine uncertainty.
If I follow ASTM test methods, and use control chart to determine my MU, would I meet ISO17025 Clause 5.4.6 requirement?
