Historical Standard: ASTM D6131-97(2004) Standard Test Method for Evaluating the Relative Tint Undertone of Titanium Dioxide Pigments
SUPERSEDED (see Active link, below)
ASTM D6131
1. Scope
1.1 This test method is intended to be used to determine the tint undertone (blue or yellow) of titanium dioxide pigments. This relates to the effective particle size of the pigment. It is based upon tinting with a black iron oxide, but other blacks may be used if found suitable.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
