Calibration of measuring equipment on-site (National Laboratory)

Purpose

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.

A calibration performed at a national laboratory fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

Method

Heavier equipment, such as measuring machines, generally must be calibrated where they stand. The National Laboratory for Length and Dimensional Metrology performs field calibrations of measuring equipment, where high accuracies are needed. We use physical standards as well as laser interferometers, depending on the properties of the measuring equipment that needs calibration. The temperature is carefully surveyed during the calibration process and when needed we make temperature corrections of the results.

Deliveries

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
