Koehler K13270 AC100 Petroleum Colorimeter
Test Method :
D156: For the determination of the color of refined oils such as undyed motor and aviation gasoline, jet propulsion fuels, naphthas and kerosine, and, in addition, petroleum waxes and pharmaceutical white oils.
D1209: Describes a procedure for the visual measurement of the color of essentially light colored liquids. It is applicable only to materials in which the color-producing bodies present have light absorption characteristics nearly identical with those of the platinum-cobalt color standards used.
D1544: This test method covers the measurement of the color of transparent liquids by means of comparison with arbitrarily numbered glass standards.
DIN6162: For the determination of iodine color.
