Fire and Sound Ratings are established at certified laboratories to the requirements of ASTM E119 or UL U263 for fire endurance and ASTM E90 for sound rated systems. The designs found on the following pages or at www.americangypsum.com/resources/design-library are summaries only, and building owners, design professionals, builders and contractors are strongly encouraged to review the listing or test report to ensure that each component of the design is being used and assembled properly on their projects. For details of a specific test, call 1-800-545-6302 ext. 5607.
