Good day all; 17025 clause 7, section 7.6.3 has some interesting language. Specifically..."where the test method precludes rigorous evaluation of measurement uncertainty, an estimation shall be made..." This appears to be a bit of loophole for non-calibration facilities. Specifically for established/common (yeah, sadly subjective terms, but as of now I have no better way to describe) methods. e.g. one could argue that fastener thread pitch measurements using pitch micrometers, "precludes rigorous evaluation", and, therefore the requirement to "evaluate measurement uncertainty" becomes an opportunity to do so via estimation only. What say all of you regarding the interpretation/application of this section? Thank you. Be well.
