1.1 This test method describes a procedure for the visual measurement of the color of essentially light colored liquids (Note 1). 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.
Note 18212;A procedure for estimating color of darker liquids, described for soluble nitrocellulose base solutions, is given in Guide D 365.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
1.4 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 6.
1.5 For specific hazard information, see the Material Safety Data Sheet.
