ASTM C1278/C1278M-07a(2015)

Standard Specification for Fiber-Reinforced Gypsum Panel

ABSTRACT
This specification covers fiber-reinforced gypsum panel. The physical properties, dimensions and tolerances, and edges of interior fiber-reinforced gypsum panels, water-resistant fiber-reinforced gypsum backing panels, exterior fiber-reinforced gypsum soffit panels, water-resistant exterior fiber-reinforced gypsum sheathing panels, interior fiber-reinforced gypsum underlayment panels, and fiber-reinforced gypsum roof board panels are presented in details. The surfaces of the fiber-reinforced gypsum panels shall be true and free from imperfections that would render the panels unfit for use with or without decoration.
SCOPE
1.1 This specification covers fiber-reinforced gypsum panels described in 1.1.1 – 1.1.4.  
1.1.1 Interior Fiber-Reinforced Gypsum Panels  
are designed to be used for walls, ceilings, or partitions and affords a suitable surface to receive decoration.  
1.1.2 Water-Resistant Fiber-Reinforced Gypsum Backing Panels  
are designed primarily 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.  
1.1.3 Exterior Fiber-Reinforced Gypsum Soffit Panels  
are designed for use on exterior soffits and carport ceilings that are completely protected from contact with liquid water.  
1.1.4 Water-Resistant Exterior Fiber-Reinforced Gypsum Sheathing Panels  
are designed for use as sheathing on buildings.  
1.1.5 Interior Fiber-Reinforced Gypsum Underlayment Panels
are designed for use as a base for application of finished flooring materials.  
1.1.6 Fiber-Reinforced Gypsum Board Panels
are designed for use in roofing systems.  
1.2 Specifications applicable to all fiber-reinforced gypsum panels are located in Sections 1 – 4 and 11 – 13 except as modified by applicable product sections. Specifications applicable to specific panels are located in the following sections:    
Interior Fiber-Reinforced Gypsum Panels  
5  
Water-Resistant Fiber-Reinforced Gypsum Backing Panels  
6  
Exterior Fiber-Reinforced Gypsum Soffit Panels  
7  
Water-Resistant Exterior Fiber-Reinforced Gypsum Sheathing Panels  
8  
Interior Fiber-Reinforced Gypsum Underlayment Panels

1.3 The values stated in either inch-pound units or SI (metric) are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independently of the other. Values from the two systems shall not be combined.  
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard.

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.
