Probabilities assume a normal distribution with standard uncertainty u = U/k about the measured value (JCGM 106). Rule agreed with the customer before calibration. | Specification: Mitutoyo Digimatic Caliper 500 series datasheet, rev 2024-03, § Table 2 (accuracy ±0.02 mm ≤ 100 mm, ±0.03 mm ≤ 150 mm) 10 mm Nominal value10\milli\metre As-found10.003\milli\metre As-left (measured)10.003\milli\metre0.0115520.9545 Conformity (as-left)PASS Tolerance limits9.98 … 10.02 mm (± 0.02 mm) Test uncertainty ratio1.73:1 Decision statement (as-left)PASS (guard-banded) 50 mm Nominal value50\milli\metre As-found50.012\milli\metre As-left (measured)50.012\milli\metre0.0115520.9545 Conformity (as-left)CONDITIONAL Tolerance limits49.98 … 50.02 mm (± 0.02 mm) Test uncertainty ratio1.73:1 Decision statement (as-left)CONDITIONAL — specification met (within tolerance) but inside the guard band, so NOT accepted under the guard-banded rule; probability of non-conformance if treated as accepted: 8.3% (normal, u = U/k) 100 mm Nominal value100\milli\metre As-found100.019\milli\metre As-left (measured)100.019\milli\metre0.0115720.9545 Conformity (as-left)CONDITIONAL Tolerance limits99.98 … 100.02 mm (± 0.02 mm) Test uncertainty ratio1.73:1 Decision statement (as-left)CONDITIONAL — specification met (within tolerance) but inside the guard band, so NOT accepted under the guard-banded rule; probability of non-conformance if treated as accepted: 43.1% (normal, u = U/k) 150 mm Nominal value150\milli\metre As-found150.011\milli\metre As-left (measured)150.011\milli\metre0.0115920.9545 Conformity (as-left)PASS Tolerance limits149.97 … 150.03 mm (± 0.03 mm) Test uncertainty ratio2.59:1 Decision statement (as-left)PASS (guard-banded)
