Quality Management

Western States Calibration operates under the requirements of ISO 17025, ISO 9001, and ANSI/NCSL Z540-1 with measuring standards traceable to the National Institute of Standards and Technology.

 

ISO 17025:2017 Decision Rules:

By default, Western States Calibration (WSC) provides statements of compliance using a binary, simple decision rule.  Decision of conformance is made solely by comparing the measurement results to the calibration limits without consideration of measurement uncertainty.  WSC's default decision rule results in an estimated Probability of False Accept (PFA) of < 50%.

If you require the use of some other decision rule, please contact us with your request.

Note: Custom decision rules may result in a price increase for your calibration services.
