Metrology Test Result Evaluation Chart

ISO/IEC 17025 Accredited Calibration, ISO/IEC 17025:2017 (section 7.1.3) states:

When the customer requests a statement of conformity to a specification or standard for the test or calibration (e.g. pass/fail, in-tolerance/out-of-tolerance), the specification or standard and the decision rule shall be clearly defined. Unless inherent in the requested specification or standard, the decision rule selected shall be communicated to, and agreed with, the customer.

In order to meet the 2% PFA (Probability of False Accept), the Northrop Grumman SSSD Metrology Services Laboratory decision rule is defined as follows (see Test Result Evaluation chart).

If you prefer a different decision rule, please reach out to your Northrop Grumman SSSD Metrology Services representative. The acceptance of Northrop Grumman Space Systems’ Decision Rule is as designated unless otherwise agreed upon in writing, prior to the start of the calibration.
