ASTM D5301-92(2024)(Practice)
Standard Practice for Physical Characterization of Paint Brushes

SIGNIFICANCE AND USE
3.1 It is important to recognize that a brush can be a mixture of several chemically different filaments or bristles, or both, in several cross sections, thicknesses and lengths. The following procedures will be helpful in identifying brush composition.
SCOPE
1.1 This practice covers the dimensions, terminology, materials and characteristics generally considered of importance to those within, or dealing with paint brushes, and describes methods of determining these parameters. This practice is not meant to be a definitive analytical method to deformulate brushes.  
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.  
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.

ASTM D5069/D5069M-13(2019)(Practice)
Standard Practice for Preparation of Paint-Roller Covers for Evaluation of Architectural Coatings

SIGNIFICANCE AND USE
4.1 Until a paint-roller cover is saturated with paint, only part of the paint loaded onto the paint-roller cover can be transferred to a surface being painted. The remainder of the paint is absorbed into the fabric of the paint-roller cover. The amount of paint absorbed by a paint-roller cover is inversely proportional to the amount already present within the paint-roller cover. By saturating the paint-roller cover before testing, quantitative inaccuracies of the amount of paint delivered to a surface are eliminated.  
4.1.1 Using a saturated paint-roller cover enables the user to apply paint at controllable spreading rates.  
4.1.2 Using a saturated paint-roller cover affords reproducibility, when repeating a test.
SCOPE
1.1 This practice covers the preparation or breaking-in of paint-roller covers for evaluation.  
1.2 This practice is applicable to paint-roller covers having nap lengths up to 13 mm [1/2 in.]. Longer pile rollers can be adapted.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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.

1.2 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.  
1.3 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 D7233-08(2017)(Test Method)
Standard Test Method for Testing Fracture of Level Paintbrush Filaments

SIGNIFICANCE AND USE
3.1 This method is intended to evaluate filaments for suitability of use in paintbrushes prior to manufacture. Filament fracture resistance is very important because paintbrushes are bent or flexed during painting and it is necessary that the filaments are not permanently deformed with usage.
SCOPE
1.1 This test method covers a procedure for determining the number of fractures present when paintbrush filaments are bent.  
1.2 This method is applicable only to monofilaments with consistent longitudinal cross sectional dimensions commonly referred to as “level” filaments.  
1.3 The values derived are in percent fractured filaments. For example, 2 fractured out of 18 filaments tested = 2/18 or 11 %.  
1.4 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.  
1.5 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.
