Flame Spread Rating Chart - Class a (or class 1) is the best fire rating. Find out the test methods and criteria for flame spread and fire resistance 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. For the purpose of applying flame spread limits to interior finish material, nfpa standard no. For example, hospitals typically require class a ratings.

Find out how paints and coatings do not affect these ratings and see examples of substrate materials. The flame spread for a class a fire rating is 25 or lower, and the smoke development does not exceed a maximum of 450. 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. Most code requirements for wood interior finish materials are expressed in terms of flame spread index numbers. Wood products have a flame spread index less than 200, making them acceptable under current building codes for a wide range of interior finish uses.
