The ASTM E1347-2003 standard describes a method for color and color difference determination using a tristimulus colorimeter (filter). This method measures the color coordinates and color difference of a sample through a hemispherical or bi-directional Optical inspection system and is suitable for samples of various Glossiness levels. Due to the accuracy limitations of tristimulus colorimeters, the standard emphasizes the use of standards with similar Light spectrum and geometric characteristics for instrument calibrating and is not suitable for chromatograph data acquisition.
