Flame Spread Rating Chart
Flame Spread Rating Chart - There are several standardized methods of determining flame spread, Differences result from factors such as density, thickness, surface characteristics, and coatings or other chemicals applied, if any. According to astm, the purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. For example, hospitals typically require class a ratings. Many facilities require a class a rating for building materials. These values are determined in a standard fire test which evaluates the surface burning characteristics of a material. Flame spread rates for lvl, psl and lsl are within the same range as solid wood materials.
Typically, at thicknesses greater than 1/4, flame spread is almost independent of material thickness. What are flame spread ratings? Most code requirements for wood interior finish materials are expressed in terms of flame spread index numbers. Learn how usg products provide fire safety and resistance with low flame spread and smoke development.
What are flame spread ratings? The icc international building code (for new buildings) and international fire code (for existing buildings) limit the allowable flame spread and smoke development characteristics of building materials used for interior finishing, based on location and occupancy type. Learn how flame spread and smoke development indexes are measured and classified for building materials according to icc and ifc codes. Find out how paints and coatings do not affect these ratings and see examples of substrate materials. Learn how flame spread and smoke developed indexes are measured and classified for building materials according to icc codes. Flame spread, or surface burning characteristics rating, [1] is a ranking derived by laboratory standard test methodology of a material's propensity to burn rapidly and spread flames.
