Calibration glossmeters & gloss standards at The National Laboratory
The National Laboratory for Photometry and Radiometry offers calibration of glossmeters and gloss reference standards.
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
RISE performs calibrations of gloss in accordance with ISO standard 2813 (or ASTMD523).
Gloss reference standards are calibrated using a glossmeter that has been calibrated against RISE high gloss standard. Calibration of glossmeters are done by direct measurement against RISE high gloss standard.
Calibration of medium gloss is calibrated in comparison with a high gloss standard as measured with a glossmeter. The transference to medium gloss increases the measurement uncertainty. The measurement uncertainty is ±1 GU for high gloss and ±2 GU for medium gloss. The measurement uncertainty also depends on the device under test.
The calibrations 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.
When becoming a client you will also get access to our customer website for calibration, where you may also place orders.
