ASTM C1921/C1921M-22

Active Standard: Standard Test Method for Comparative Impact Testing of Gypsum Panel Outside 90° Corner Systems

ASTM C1921/C1921M

Scope

1.1 This test method details the method for a laboratory-based evaluation of aesthetic damage caused to a non-structural gypsum panel outside 90° corner system when impacted by a hard body. This test’s purpose is to provide comparative information on different gypsum panel corner systems to demonstrate aesthetic robustness and durability by minimizing initial damage.

1.2 There is no known ISO equivalent to this standard.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 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.
