NATA class of test 1.63

ORLAB is NATA accredited for calibration and measurement of light sources for luminance

from 0.1 cd.m-2

with least uncertainty of

1.5% or 0.01 cd.m-2 (whichever is the greater) for incandescent lamps with or without broadband filters and
2.0% or 0.01 cd.m-2 (whichever is the greater) for other sources.

These measurements can also be made on-site.

Based on sources calibrated by the National Measurement Institute, Australia and surfaces calibrated by the National Research Council of Canada and the National Physical Laboratory.
