There are several standardized methods of determining flame spread. Class Flame Spread Index A B C In order to meet classification in any of the three categories, the smoke developed index cannot exceed This page was last edited on 14 Augustat The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source.
Evaluation of a FSI by this test method does not provide a good understanding of how fire would propagate in full scale, such as in a room, for some materials. In order to meet classification in any of the three categories, the smoke developed index cannot exceed Link to Active This link will always route to the current Active version of the standard.

The result is derivation r84 a Flame Spread Index FSI which is a non-dimensional number which is placed on a awtm scale in which asbestos-cement board has a value of 0, and red oak wood has These test results do not necessarily relate to indices obtained by testing materials without such support.
ASTM E84 – 07 Standard Test Method for Surface Burning Characteristics of Building Materials
Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side. Referenced Documents purchase separately The documents listed satm are referenced within the subject standard but are not provided as part of the standard.
Flame spread or surface burning characteristics rating  is a ranking derived by laboratory standard test methodology of a material’s propensity to burn rapidly and spread flames. This standard does not purport to address all of the safety concerns, if any, associated with its use.
American NFPA / ASTM E 84
However, there is not necessarily a relationship between these two measurements. 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. The material, product, or assembly shall be capable of being mounted in the test position during the test.
This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test.

Flame spread and smoke developed index are reported. The following standards address testing of materials in accordance with test methods that are applications or variations of the test method or apparatus used for Test Method E Also, test results for heat, smokeand combustion product release from NFPA are suitable e884 use as input into fire ashm for performance-based design, whereas results from NFPA are not.
This method is more indicative of real world fire hazards, and is preferred over NFPA but is more expensive. From Wikipedia, the free encyclopedia.
