Quick Facts

Overview

    ASTM Committee C11 on Gypsum and Related Building Materials and Systems develops voluntary consensus standards for ASTM International, a not for profit organization based in West Conshohocken, PA. ASTM is not a trade association, but provides a member-based, open standards development process, using ASTM’s advanced infrastructure.

    Subcommittee C11.01, with a current membership of 120, focuses on standard specifications and test methods for gypsum products and gypsum board. The subcommittee consists of a balance of producers, users and general interest members from key industry stakeholders, including gypsum manufacturers, government representatives from the Consumer Product Safety Commission (CPSC) and National Institute of Standards & Technology (NIST), trade associations as well as architects and engineers.

Background

Current Update

    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 Storage of Gypsum Panel Products. The standard provides the CPSC, states, suppliers and consumers with an effective tool for supply chain communication by specifying that each gypsum panel product or package must be marked for the thickness, the name of the producer or supplier, the brand name, if any, and the ASTM specification for the product. The 2011 version of Standard C1264 expanded the labeling requirements to identify drywall by manufacturer, date made and country of origin. The inclusion of ASTM C1264 in the Drywall Safety Act will help builders and consumers better understand the origin and source of drywall and other gypsum products.

Sulfur Content

    The Drywall Safely Act requires that the CPSC issue a regulation that limits the sulfur content for drywall manufactured or used in the United States. Several standards are in the process of being revised that will establish a limit of orthorhombic sulfur in gypsum products.

    Work Item WK33245 New Test Methods for the Analysis of Gypsum and Gypsum Panel Products for Impurities continues to work on a series of methods that will be used to identify impurities in drywall suspected of emitting sulfide compounds. This work item will be the repository for the development of future test methods used to test for this contamination.
