ASTM D6904-2022 《Standard Practice for Resistance to Wind-Driven Rain for Exterior Coatings Applied on Masonry》 Related products

The standard specifies a method for testing the weatherability of Coatings on masonry structures. The method is designed to simulate the performance of a coating system under exposure to continuous water spraying and dynamic pressures equivalent to 98 mph wind speeds to assess whether it will experience water leakage or weight gain. The test assesses the durability and protection of Coatings by simulating actual environmental conditions. The standard emphasizes the use of inch-pound units, SI unit values are for informational purposes only, and requires users to establish appropriate safety and environment practices prior to use.
