(Specification)Standard Specification for Factory-Laminated Gypsum Panel Products
Standard Specification for Factory-Laminated Gypsum Panel Products
ABSTRACT
This specification establishes the requirements for factory-laminated gypsum panel products designed for use either on walls, ceilings, or partitions as part of a sound control system, or as a gypsum stud or gypsum coreboard. It covers materials and manufacture, physical properties, dimensions and tolerances, finish and appearance, sampling, inspection, rejection, certification, packaging, marking, shipping, handling, and storage.
SCOPE
1.1 This specification covers the factory-laminated gypsum panel products designed either for use on walls, ceilings, or partitions as part of a sound control system; or for use as a gypsum stud or gypsum coreboard.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 non-conformance with the standard.
1.3 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 safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
