ASTM D6131-17(2023)(Test Method)
Standard Test Method for Evaluating the Relative Tint Undertone of Titanium Dioxide Pigments

SIGNIFICANCE AND USE
5.1 This test method allows the user to make a determination of the blueness or yellowness of the tint undertone of titanium dioxide pigments, versus a reference pigment agreed upon by the parties to the test. This is an important measure of tone, since it gives both a measure of effective particle size, and quick approximation of the blue/yellow undertone that can be expected when a coating containing the titanium dioxide is tinted.  
5.2 Such matters as the vehicle for preparing the dispersions and the mechanical method of preparing the dispersion are left to the user. However, variation in these practices will lead to increased variance in the results, so users ought to fix these parameters, in-so-far as is possible, within any one laboratory. This will lead to reduced uncertainty of the results within that laboratory, and it is seldom that interlaboratory comparisons of this test result is needed.  
5.3 Each user must decide whether the loss of accuracy in his measurements due to variation of these parameters is negligibly small for the purpose for which the data are obtained.
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  
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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 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.

Standard Test Method for Relative Tinting Strength of White Pigments by Reflectance Measurements

SIGNIFICANCE AND USE
4.1 Tinting strength is one of the most important properties of a white pigment. This test method provides a means of testing this property for quality control.  
4.2 This test method is a referee method, and the vehicle for preparing the dispersion and the black for tinting are suggested, but others may be used provided both the purchaser and the seller agree to the changes.  
4.3 The results obtained with a muller do not necessarily agree with industrial situations where different dispersing conditions exist. However, dispersing with a muller is a fast, relatively inexpensive way of testing tinting strength for routine quality control.
SCOPE
1.1 This test method describes the procedure for determining the relative tinting strength of white pigments by reflectance measurements of black tints.  
1.2 This test method is applicable only for comparing the test pigment with a reference standard of the same type and grade.  
Note 1: Test Method D332 describes a procedure for visual assessment of blue-tinted samples.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Methods for Coarse Particles in Pigments

SIGNIFICANCE AND USE
3.1 In production of paints, smoothness of the paint film is of paramount importance. Agglomerates or coarse particles larger than 45 μm are difficult to disperse and may prevent obtaining a smooth film. These test methods are a valuable quality control test for grading raw materials.
SCOPE
1.1 These test methods cover the determination of the amount of coarse particles in dry pigments.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D6619-00(2023)(Practice)
Standard Practice for Incorporating Pigments by High Speed Dispersion

SIGNIFICANCE AND USE
3.1 High speed dispersion is a commonly used dispersion method in the coatings industry. For the purpose of this practice, “high speed” would normally be understood to be a range of RPM between 3 000 and 10 000. This practice provides a reference for its use, so that a producer and user can standardize on an incorporation technique. This will minimize differences in the millbase, and allow the interested parties to concentrate on the physical, chemical, or optical methods to be run.
SCOPE
1.1 This practice covers the dispersion of pigments using a laboratory size high-speed impeller mill. It is similar in technical content to ISO 8780-3.
Note 1: This practice is restricted to mill bases of moderately high viscosity due to either high vehicle concentration or high pigment concentration, or both, which can produce high shear force. It is not intended to provide a means of formulating either pilot plant or full-scale mill base compositions (scaling up the process from laboratory equipment to factory mills is not simple).  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 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.
