Calibration of angles at The National Laboratory

The National Laboratory for Length and Dimensional Metrology offers calibration of both artefacts and instrument. Some examples are stock squares, try squares, carpenter’s squares, squareness standards made of diabase or steel, universal protractors, protractors, digital protractors, water levels and inclinometers.


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. 


Calibration of squareness standards is performed up to 500 mm. The calibration is performed against a reference standard on a surface plate. Indicating instruments such as universal protractors, protractors, digital protractors and water levels are calibrated using a sine bar and gauge blocks, alternatively with an indexing table.  Accurate inclinometers from 0,001 mm/m are calibrated on a sine bar of diabase with a laser interferometer as reference.


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.
