ASTM C1278/C1278M-17 is a standard specification that covers various types of fiber-reinforced gypsum panels used for different purposes. The standard specifies the physical properties, dimensions, tolerances, and edges of the panels, ensuring that they are suitable for their intended use.

The standard covers six types of fiber-reinforced gypsum panels, which are described in sections 1.1.1 to 1.1.6. These panels include interior panels used for walls, ceilings, or partitions, water-resistant backing panels used as a base for ceramic or plastic tiles, exterior panels for soffits and carport ceilings, water-resistant exterior sheathing panels, interior underlayment panels used as a base for finished flooring materials, and roof board panels for roofing systems.

The specifications for all fiber-reinforced gypsum panels are located in sections 1-4 and 11-13, with modifications specified in the applicable product sections. Each type of panel has its own dedicated section, detailing the specific requirements.

It is important to note that the standard includes references to explanatory notes and footnotes, which provide additional information but are not considered as mandatory requirements of the standard.
