Standard Test Method for Exposure of Firestop Materials to Severe Environmental Conditions
 N E2785

Annotation

This 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.

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

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

NOTE 1—This test method does not preclude the possibility of exposing complete firestop systems to one or more severe environmental exposures and then exposing the complete firestop system to a fire test.

This 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.

The 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.

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 and health practices and determine the applicability of regulatory limitations prior to use.
