ASTM E 2785 : 2025 : REV A

1.1This practice evaluates a change in physical properties of firestop materials after exposure to an enhanced environmental factor. This practice does not evaluate the fire performance of the firestop materials.

1.2This practice uses the following exposures:

1.3This practice establishes indicators that will aid in determining the use of the tested material in buildings.

1.4This practice evaluates the properties of component products used within a firestop system, and does not evaluate the properties of assembled firestop systems.

1.5This practice is intended to be a screening method in the evaluation of the change in physical properties of a specific material before and after various specified enhanced environmental factors. Individual tests are not intended to be the only determining factor in evaluating or selecting a firestop material because each test has limitations.

1.6The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.7This 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.

1.8This 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.
