Meaning and use

5.1 Latex paints are sometimes applied to substrates containing highly water-soluble salts, resulting in weathering. This approach assesses the coating’s vulnerability to weathering.

ASTM D7072-19 Standard Practice for Evaluating Accelerated Fluorescence of Latex Coatings

Step 1: Scope

1.1 This practice includes assessing the extent to which the latex paint resists formation weathering and alkali burn-out on exposed paint surfaces.

1.2 The main purpose of this practice is to relate weathering originating from the substrate to the presence of deposits on the surface of the latex paint. This practice mainly involves the coating of masonry type substrates, such as concrete blocks, bricks, mortar, stucco, poured concrete and similar materials.

1.3 Values expressed in SI units shall be considered standard. The values in parentheses are for reference only.

1.4 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.

1.5 The international standard is based on internationally recognized standardization principles established in the “Decision on Principles for the Development of International Standards, Guidelines and Recommendations” issued by the Committee on Technical Barriers to Trade (TBT) of the World Trade Organization.
