ASTM D1209 Test Method for Color of Clear Liquids (Platinum-Cobalt Scale)
1. Scope
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 1 - A procedure for estimating color of darker liquids, described for soluble nitrocellulose base solutions, is given in Methods D365.
1.2 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.
1.3 For specific hazard information, see the Material Safety Data Sheet.
