ASTM E 2768 : 2011 : R2018

1.1The purpose of this fire-test-response standard is to evaluate the ability of a product to limit the surface spread of flame when evaluated for 30 min. This fire-test-response standard uses the apparatus and procedure of Test Method E84 with the total test period extended to 30 min.

1.2Building applications affecting fire and life safety often require products with specific criteria for surface spread of flame and flame spread index. The resulting performance characteristics included in the conditions of classification for this fire-test-response standard are intended to be used for regulatory purposes to determine the suitability of materials or products for use in buildings under specified conditions where significantly reduced surface burning characteristics are required.

1.3Materials and products that are beyond the scope of Test Method E84 are beyond the scope of this standard.

1.4Materials or products which melt, drip or delaminate to the extent that the continuity of the flame front is destroyed are beyond the scope of this standard.

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.

1.6The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding tables and figures, shall not be considered as requirements of the standard.

1.7This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions

1.8This 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.

1.9Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.10This 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.
