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 against CIE Standard Illuminant A (2856K) and can be performed at any illumination level from 0,1 lux to 500000 lux. Instruments that measure illuminance in foot-candles 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 illuminance levels above 20000 lux. 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.
