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.View Less
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.
