Mold Growth on Exterior Building Materials Is Subject of Proposed New ASTM Standard
Consumers who are purchasing building materials for homes want to be assured that the materials are mold resistant. A proposed new ASTM standard will allow for a mold-resistance rating to be given to specific materials, depending on how the materials perform to the test method. The proposed new standard, ASTM WK32079, Test Method for Determination of Mold Growth on Building Products Designed for Exterior Applications Using an Environmental Chamber and Direct Inoculation, is being developed by Subcommittee G03.04 on Biological Deterioration, part of ASTM Committee G03 on Weathering and Durability.
