ASTM drafting new paint test standard

摘要

ASTM International is proposing a new architectural paint and stain test method aimed at standardizing testing for dirt repellency across the industry. Coating suppliers and manufacturers will be the primary users of ASTM WK38233, Test Method for Dirt Pick-Up Resistance for the Films of Architectural Paints and Stains, which will combine various existing in-house methods for testing dirt pick-up resistance, according to ASTM. Paints differ greatly in their ability to repel dirt, dust particles and other debris. The new standard is designed to standardize methods for testing dirt repellency.
