Flame Spread and Smoke Development PEH 9-20-2011 Rev. 5-3-2013 Page 1 of 1 i The Flame Spread Index is a comparative measure, expressed as a 3 Jul 2014 A flame spread index of 0–25, as determined by the ASTM E84 test, is Class A; flame spread of 26–75 is Class B, and 76–200 is Class C. A Flame spread index. H. Horizontal test. HOC. Heat of combustion. HRP. Heat release parameter. HRR. Heat release rate. ICAL. Intermediate-Scale Calorimeter. The Initial Spread Index (ISI) is a numeric rating of the expected rate of fire spread. It combines the effects of wind and the FFMC on rate of spread without the Flame spread and smoke developed indexes are reported. However, there is not necessarily a relationship between these two measurements. This standard is Understanding Flame Spread Ratings What is a flame spread index? It's time to clear the air and extinguish any misperceptions of flame spread ratings and how they apply to architectural paints. Quite simply, paints are not required by The ICC International Building Code (for new buildings) and International Fire Code (for existing buildings spread-of-flame index flame-spread index A numerical designation, applied to a building material, which is a comparative measure of the ability of the material to resist flaming combustion over its surface; the rate of flame travel, as measured under the applicable ASTM test, in which a selected species of untreated lumber has a designated

The ISI is a measure of the head fire indicator and rate of fire spread. The higher ISI index indicates higher difficulty of control in grassland. It is a combination of

Firefree Class A, Flame Spread Index zero (0), minimal thickness of 10 mils (.010 inch) dry application, it also meets the requirement for smoke developed index Code officials and regulatory agencies frequently use the Flame Spread Index and. Smoke Developed Index values obtained by the NFPA 255/ASTM E-84 test The BCA sets requirements for flame spread and smoke release. non- combustible material is required it is to have a spread of flame index not greater than 0.

during the test. Materials are classified into one of three groups based on their tested flame spread characteristics. These groups and their flame spread indexes ASTM E162 is used to assess flame spread via a radiant panel index. This test method is frequently used in regulations, particularly for transportation means the index number for spread of flame as determined by AS/NZS 1530.3. 5.2.10 Stage. means a floor or platform in a Class 9b building on which 18 Apr 2016 the Spread-of-Flame Index and the Smoke-Developed Index of the laminated material as a whole does not exceed 0 and 3 respectively. CSIRO Standard test method for surface burning characteristics of of building materials. The flame spread Index and Smoke Developed Index values obtained by the Sometimes it is necessary to know the fire characteristics of materials that are The flame spread and smoke development indexes are then calculated and

The BCA sets requirements for flame spread and smoke release. non- combustible material is required it is to have a spread of flame index not greater than 0.

A Class 1 surface spread of flame (in accordance with BS 476: Part 7) material which has a fire propagation index (I) of not more than 12 and a sub-index (i1) of not

spread-of-flame index flame-spread index A numerical designation, applied to a building material, which is a comparative measure of the ability of the material to resist flaming combustion over its surface; the rate of flame travel, as measured under the applicable ASTM test, in which a selected species of untreated lumber has a designated

0–25 flame-spread—Class A Enclosed vertical exits 26–75 flame-spread—Class B Exit access corridors 76–200 flame-spread—Class C Other rooms and areas The model building codes require a smoke-developed index of 450 or less for most construction applications. Designers should consult their locally applicable codes for flame-
