ASTM E 2785 : 2014 : R2022

1.1This test method evaluates a change in physical properties, chemical properties, or both, of firestop materials after a standardized environmental exposure. This test method does not evaluate the fire performance of the firestop materials.

1.2This test method establishes indicators that will aid in determining the use of the tested material in buildings.

1.3This test method evaluates the properties of component products used within a firestop system, and does not evaluate the properties of assembled firestop systems.

1.4This test method is intended to be a screening method in the evaluation of the relative behavior of a specific material before and after a standardized set of severe exposure criteria. Individual tests are not intended to be the only determining factor in evaluating or selecting a firestop material because each test has limitations.

1.5The 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.

1.6This 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.

1.7This 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.
