ASTM C1658/C1658M-12

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:
  Section Glass mat interior gypsum panel5 Glass mat coreboard gypsum panel,
and glass mat shaftliner
gypsum panel6 Glass mat water-resistant gypsum panel7
1.3 The values stated in either inch-pound units or SI (metric) are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independent of the other. Values from the two systems shall not be combined.
