Purpose
The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competens 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 fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large.
Method
The calibration is performed according to existing international standards and recommendations.
The calibration is performed against luminance source with CIE Standard Illuminant A (2856K) and can be performed at any luminance level from 0,01 cd/m2 to 500000 cd/m2. Instruments that measure luminance in foot-lamberts can also be calibrated. The standard service has a measurement uncertainty of 3% as a base but the measurement uncertainty can increase depending on the properties of the device under test as well as for luminance levels above 200000 cd/m2. If a lower measurement uncertainty is required then that can be discussed as a speciality service.
The calibration takes place at the laboratory for photometry and radiometry in Borås.
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.
