System Audit
The right audit solution for every application
High degree of comparability and metrological traceability of readings
The various measuring instruments from Instrument Systems combine the highest precision and reliability with the best-possible repeatability and stability. An outgoing inspection by our test lab accredited to DIN EN ISO/IEC 17025:2005 (D-PL-19052-01-00) guarantees a high degree of comparability and metrological traceability of the readings.
The challenge: Reliable readings in the long term
To ensure this comparability over a longer period of time, the measuring instruments should be checked at regular intervals to verify that they adhere to specified tolerance limits.
Independent samples (auditing) ensures that (device) specifications are adhered to. Addition to quality control, a consistency check of the entire measuring equipment chain also takes place.
Typical audit process
〮 Use of three stable standards
〮 Successive measurement of standards in defined measurement geometry
〮 Verification of readings against specific reference and limit values
〮 Evaluation of results according to the majority principle
〮 Repeat at regular intervals
〮 Documentation and statistical evaluation of measurement data and results
