SIGNIFICANCE AND USE
4.1 Surfactant staining is a common problem with exterior house paints, particularly when subjected to humid environments (such as morning dew) shortly after application.  
4.2 Interior paints used in humid areas such as kitchens and bathrooms may also experience surfactant staining.  
4.3 Leaching of water-soluble materials may be dependent on colorant dispersions that are mixed into tint base paints. Other paint components may also affect the leaching of water-soluble materials.
SCOPE
1.1 This practice covers the ability of a latex paint film to resist staining caused by the leaching of water-soluble materials when contacted with water shortly after application.  
1.2 Water staining is attributed to the leaching of surfactants or other water-soluble materials from a paint film.  
1.3 The values stated in SI units are to be regarded as standard.  
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.

ASTM D4287-00(2023)(Test Method)
Standard Test Method for High-Shear Viscosity Using a Cone/Plate Viscometer

SIGNIFICANCE AND USE
4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D4958), spraying, electrostatic disk, or roll coating.  
4.2 This test method is suitable for all paints and varnishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment dispersions as determined by Test Method D1210.
SCOPE
1.1 This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s−1.  
1.2 Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.  
1.5 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 Practice for Short Term Vehicle Service Exposure of Automotive Coatings

SIGNIFICANCE AND USE
4.1 Since the exposure of automotive coatings to the various mechanical and chemical stresses encountered in actual operations, is very opportunistic, obtaining statistically significant data from which valid conclusions can be drawn, requires rigorous attention to the experimental designs and conditions of exposure.
SCOPE
1.1 This practice covers the protocol for vehicle service exposure testing of automotive coatings. Such exposure testing is valuable for the verification of the performance of automotive coatings and correlation with laboratory test data. Vehicle service exposure is intended to provide short term (2 to 20 weeks) exposure to the stress factors associated with vehicle operation. Factors included are scratch, mar, impact, stone chipping, insect impact, bird dropping, tree sap and staining, environmental fallout, etc.
Note 1: Vehicle service exposure is not intended to provide the conditions that are needed for characterizing the long term effects of weathering or corrosion exposure.  
1.2 The exposure conditions are produced by the placement of multiple test panels of automotive finishes on automotive test fleets that traverse a defined road course. Exposure to the operating environment can be 20 h/day, 7 days/week allowing for accumulation of over 100 000 miles in 10 weeks of exposure.  
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.

ASTM D2805-11(2023)(Test Method)
Standard Test Method for Hiding Power of Paints by Reflectometry

SIGNIFICANCE AND USE
5.1 This is a precise instrumental method giving results having an absolute physical significance without reference to a comparison paint. It should be used when maximum precision and minimum subjectivity are required, as in testing specification coatings or evaluating the hiding efficiency of pigments.  
5.2 Hiding power Test Method D344 is visual instead of instrumental, and gives results that are relative to a material standard instead of absolute. It is less precise than Test Method D2805 but more closely aligned with practical painting procedures.
SCOPE
1.1 This test method covers the determination, without reference to a material paint standard, of the hiding power of air dry coatings with Y tristimulus values greater than 15 %. With appropriate modification, it can also be used to test baking finishes.  
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.

ASTM D6762-18(2023)(Test Method)
Standard Test Method for Determining the Hiding Power of Paint by Visual Evaluation of Spray Applied Coatings

SIGNIFICANCE AND USE
5.1 This test method determines hiding power of a test paint by visual evaluation of a spray applied coating.
Note 1: Test Method D2805 describes an instrumental method for determining hiding power. The paint film is applied at a uniform thickness (for example with a doctor blade), the film thickness is measured rigorously, and the opacity is determined photometrically. Hiding power is thereby determined with a high degree of precision.  
5.2 Test Method D6762 is less precise than Test Method D2805, but is commonly used since it is more closely related to the application characteristics of the paint and is simpler in concept and evaluation.
SCOPE
1.1 This test method provides for the quantitative visual determination of the film thickness required to achieve full hiding. This film thickness is considered to be the hiding power of a test paint.  
1.2 This method applies only to spray applied coatings but its concepts are valid for other methods of application as well.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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.  
1.5 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.
