Color Analysis ASTM D6290, ASTM E1347, ASTM E308

Color Analysis: Hunter Lab, CIE Lab, ASTM D6290, ASTM E1347, ASTM E308

Scope:
Hunter Lab and XYZ are standard three dimensional color spaces that allows a precise definition of the color of a test sample. Color analysis can be used to match adjacent parts molded from different materials, or to evaluate color change due to outdoor exposure. Visual color and spectrophotometer readings can also be affected by surface texture, molding parameters, processing method, and viewing light sources.

Test Procedure:
The BYK Gardner Spectrophotometer is highly automated. After specifying the illuminant, observer angle, and the reference color, the test sample is inserted into the specimen holder and the spectrophotometer takes the reading.

Specimen size:
Typically a 50 mm (2") or 100 mm (4") disk

Data:
Hunter Lab
XYZ
CIE Lab
