Station Status Designations:
Class-1 An active metrology station for which continuous traceability is maintained by internal redundancy, cross checks, and periodic recalibration of primary standards by external agency. Uncertainties established by accepted statistical treatment of historical data. Customers are charged the established hourly rate for direct calibration time for their instrument.
Class-2 A metrology station for which we have sufficient equipment to perform a traceable calibration but the equipment is not maintained under current statistical control. A setup and precalibration may be required before performing calibrations. Uncertainties are established by statistical analysis of pre-cal and cal data from the current calibration. No historical tracking is done. Customers are charged the established hourly rate for direct calibration time for their instrument, but not for set-up and pre-cal time unless negotiated in advance.
Class-3 A special calibration or test for which we have the necessary equipment and experience, but may require setup and pre-cal before performing the test. These tests are negotiated individually with the customer on a full cost recovery basis.
