1、Designation: C1766 13C1766 15Standard 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

2、number in 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 gypsum panel products designed either for use on walls, ceilings, orpartitions as part

3、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 unitsare shown in brackets. The values stated in each system may not be exact equivalents; theref

4、ore, each system shall be usedindependently 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 responsibilityof the user of this stand

5、ard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
