Published by ASTM International, 12/01/2017
ASTM C1177/C1177M, 2017 Edition – Standard Specification for Glass Mat Gypsum Substrate for Use as Sheathing
ASTM C1177 covers glass mat gypsum substrate, which is designed to be used as an exterior substrate for a weather barrier.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

04.01: Cement; Lime; Gypsum
Volume 04.01 features specifications and test methods that establish the property requirements and measurement procedures for hydraulic cements, including portland, natural, pozzolanic, masonry, rapid hardening, and slag.
It includes standards that define the appropriate qualities of lime and limestone and how to analyze them for environmental and industrial uses.
The remaining standards in this volume address gypsum and related building materials and systems, including application procedures and related accessories, including exterior insulation and finishing systems (EIFS).
ASTM’s Manual of Cement Testing, a valuable companion to these standards, also appears in this volume.
