1.1 This practice covers the installation requirements of screw attached T-bar-type gypsum board ceiling systems constructed as flat, single level, surrounded on all sides by a wall, bulk head, or soffit braced to the building structure to resist the effects of earthquake ground motions. 1.2 Ceiling assembly shall not be accessible to support live loads. 1.3 Units--The values stated in either SI unit or inch pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate standard safety and health practices and determine the applicability of regulatory limitations prior to use. 1.5 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
