ASTM C1264 Addresses Origin and Source Labeling of Drywall and Other Gypsum Products, In response to the importation of contaminated drywall that caused health and safety hazards when used in home construction, the Drywall Safety Act of 2012 (PL 112-266) was signed into law by President Barack Obama on Jan. 14, 2013. The new law cites ASTM International standard C1264-11 , Specification for Sampling, Inspection, Rejection, Certification, Packaging, Marking, Shipping, Handling and…, Labeling, The Drywall Safety Act requires the CPSC to set regulations based on C1264 , which was developed by ASTM Subcommittee C11.01 on Specifications and Test Methods for Gypsum Products , part of ASTM Committee C11 on Gypsum and Related Building Materials and Systems . The standard provides the CPSC, states, suppliers and consumers with an effective tool for supply chain communication by specifying…, Up-to-Date Standards, Under the act’s provisions, ASTM International will notify the CPSC of any updates to the labeling standard within 60 days; the CPSC will then have 90 days to disapprove ASTM’s recommended changes. If the CPSC accepts the most updated version of the ASTM standard, then the new version becomes effective 180 days after ASTM’s initial notification., Sulfur Content, Because sulfur content levels in drywall have been associated with elevated corrosion rates in a home, the act requires that the CPSC issue a regulation that limits the sulfur content for drywall manufactured in the United States or imported from abroad. In lieu of issuing a federal rule, the CPSC may adopt a voluntary consensus standard, developed by C11.01, that addresses the level of sulfur…, ASTM Staff Contact:, Thomas O’Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9277
