In addition to metrological quality controls, the visual control of color matches is also very important.
The ISO 3668, ASTM D1729 and DIN 6173-2 standards specify a mandatory benchmark for visual color comparisons used in different industries. These describe all the parameters, such as the implementation, viewing and environmental conditions, that are required to ensure a standardized color comparison. The JUST daylight 6500 proIndustry fluorescent lamp complies with these strict standards and as a result creates controlled and reproducible lighting conditions for the standardized matching of a wide range of materials.
