* SFI TECHNICAL BULLETIN 3.2 EFFECTIVE: MAY 22, 2012 SUBJECT: Fire Protection Material 1.0 GENERAL INFORMATION SFI Technical Bulletin 3.2 consists of test procedures for fire protection material. In this bulletin, the word material is used to connote any single layer fabric or multiple layer combination of fabrics. 2.0 OBJECTIVE SFI Technical Bulletin 3.2 consists of two test procedures for fire protection material. One determines the Thermal Protective Performance {TPP} rating of the material and the other is a test of flammability. A procedure for each test is contained herein. 3.0 TESTING 3.1 TPP TEST This test exposes a material to the heat from a standard source and measures the amount of heat energy which, when applied to one side of the material, to exceed time- to-thermal energy limits on the other side as represented by a performance curve commonly known as the “Stoll Curve”. The material is rated for thermal resistance and insulation when exposed to a 50%/50% combination of convective and radiant energy at 2 2 a level of about 2.0 cal/cm -sec (8.37 W/cm ) for a short duration {cal = calories, cm = centimeter, sec = second, W = watts}. The TPP rating is a measure of the exposure energy. This method is similar, but not identical, to the ASTM F 2700-08 Standard Test Method for Unsteady-State Heat Transfer Evaluation of Flame Resistant Materials for Clothing with Continuous Heating.
