Application Summary AI generated
This standard specifies a test method for measuring the rate and total quantity of sulfate ions (SO42-) released from gypsum materials when exposed to water. It is applied in the construction industry to evaluate the potential for gypsum-based products, such as plasters, blocks, and boards, to cause sulfate attack on concrete or corrosion of embedded metals in building environments. The method is used for quality control and environmental safety assessments of gypsum materials in contact with moisture.
