1.1 This test method covers the automatic determination of color of a wide variety of petroleum products such as undyed motor and aviation gasoline, aviation turbine fuels, naphthas, kerosine, pharmaceutical white oils, diesel fuel oils, heating oils, and lubricating oils by the automatic tristimulus method. This test method correlates to Test Method and Test Method as calculated by the instrumentation.
Note 1: With the appropriate sample handling, this test method would apply to petroleum waxes, but they were not used in the round robin, and the precision of this test method with regard to waxes is unknown.
1.2 This test method reports results in terms of Test Method or Test Method .
1.3 This test method has a one-to-one correlation for the entire range of Test Method ASTM Color and for the range from 0 to +30 for Test Method Saybolt color.
1.4 This test method does not apply to solid samples, petroleum products containing dye, and petroleum products having extreme fluorescence.
1.5 This test method does not apply to cloudy samples. Such samples shall be filtered so they are clear before measuring.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
