1.1 This test method describes a procedure for the visual measurement of the color of near-clear 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. 1.2 This test method has been found applicable to the color measurement of clear, liquid samples, free of haze, with nominal platinum cobalt color values between 0 and 100. It is applicable to nonfluorescent liquids with light absorption characteristics similar to those of the platinum cobalt color standard solutions. Test Methods D1209, D1686, D5386, and E450 deal with the visual and instrumental measurement of near-clear liquids. 1.3 In determining the conformance of the test results using this test method to applicable specifications, results shall be rounded in accordance with the rounding off methods of Practice E29. 1.4 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.5 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. For specific hazard statements see Section 7.
