Calibration standards for form measurements at The National Laboratory

The National Laboratory for Length and Dimensional Metrology offers calibration of form standards intended for use with form measuring devices.


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. 


Form measurements includes parameters such as roundness, cylindricity, straightness and flatness. The definitions of these parameters will be found in ISO 1101. Roundness standards, reference cylinders, straightness standards and flatness standards are calibrated in accordance with these definitions. We offer also calibration of measuring instruments for form and amplification standards for roundness testers. The measuring methods that are used in the calibrations are based on tactile measurements.


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.


Order can be sent to, or through the case management in our customer website Calibration.
