Standard Specification for Glass Mat Gypsum Panels
ABSTRACT
This specification covers the glass mat gypsum panels. Glass mat interior gypsum panel, designed for use on walls, ceilings, or partitions and that affords a surface suitable to receive decoration. Glass mat coreboard gypsum panel, and glass mat shaftliner gypsum panel, designed for use as a base in multilayer systems or as gypsum studs or cores in semisolid or solid gypsum board partitions, or in shaftwall assemblies. Glass mat water-resistant gypsum panel, designed to be used as a base for the application of ceramic or plastic tile on walls or ceilings. Glass mat gypsum panel shall consist of a noncombustible core, gypsum, surfaced with glass mat partially or completely embedded in the core. Flexural strength, humidified deflection, null pull resistance, water resistance, and surface water absorption and shall conform to the physical property requirements of the materials specified.
SCOPE
1.1 This specification covers the glass mat gypsum panels described in 1.1.1 – 1.1.3.
1.1.1 Glass mat interior gypsum panel, designed for use on walls, ceilings, or partitions and that affords a surface suitable to receive decoration.
1.1.2 Glass mat coreboard gypsum panel, and glass mat shaftliner gypsum panel, designed for use as a base in multilayer systems or as gypsum studs or cores in semisolid or solid gypsum board partitions, or in shaftwall assemblies.
1.1.3 Glass mat water-resistant gypsum panel, designed to be used as a base for the application of ceramic or plastic tile on walls or ceilings. This product is also suitable for decoration. (This is distinct from a coated glass mat water-resistant gypsum panel ASTM 1178.)
1.2 Specifications applicable to all glass mat gypsum panels are located in Sections 1 – 4 and 8 – 10. Specifications applicable to specific glass mat gypsum panels are located in the following sections:

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
