1、Designation: C1766 13Standard Specification forFactory-Laminated Gypsum Panel Products1This standard is issued under the fixed designation C1766; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i

2、n parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the factory-laminated gypsumpanel products designed either for use on walls, ceilings, orpartitions as part of a soun

3、d control system; or for use as agypsum stud or gypsum coreboard.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each sy

4、stemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establis
