Accredited Calibrations
SIMCO’s ISO/IEC 17025:2017 accredited calibration offerings include the full set of pre and post adjustment measurement data (including Out Of Tolerance data) with uncertainties. SIMCO customers have two 17025 accredited calibration options to choose from:
- 17025 Accredited with Simple Decision Rule – default option
Decision of conformance is made solely by comparing the measurement result to the calibration limits. This option is SIMCO’s default decision rule. See illustration below:
- 17025 Accredited with Guard Banded Decision Rule, based on TUR
Decision of conformance considers measurement uncertainties. It uses an algorithm based on the Test Uncertainty Ratio (TUR) and produces a probability of false acceptance (PFA) of ≤ 2%. This option controls the risk of false acceptance (accepted as in-tolerance but is actually out-of-tolerance) at the cost of increased false rejection (rejected as out-of-tolerance but is actually in-tolerance). This option is higher priced than the Simple Decision Rule option. See illustration below:
