Test Method
The ASTM color of petroleum products applies to products having an
ASTM color of 0.5 or darker, including lubricating oils, heating oils and
diesel fuel oils. (For products having an ASTM color lighter than 0.5,
use the Saybolt Chromometer.) To determine ASTM color, the sample is
compared against standard color discs in the Petroleum Colorimeter.
Petroleum Colorimeter
. Conforms to ASTM D1500 specifications
Single scale, 3-field petroleum comparator designed for visual color
grading by direct comparison between the sample and colored glass filters
housed in test discs conforming to the chromaticity coordinates of ASTM
D1500. The sample and two consecutive glasses on the color scale are
viewed simultaneously, making it easier to achieve the optimum color
match. For rapid color grading within predetermined color limits, the glass
standards can be set to the two limiting colors so that it is easy to check
that the sample is within tolerance. The tungsten halogen light source
is color corrected to CIE Standard Illuminant C, giving constant lighting
conditions for color grading, regardless of ambient lighting. A prism brings
the three fields together to aid color grading.
