FYI: ASTM E84 is one of the most widely recognized fire tests in the building industry because it measures flame-spread and smoke-development characteristics. Achieving a Class A rating is a significant milestone and removes what could have been a major obstacle to commercial acceptance. In many applications, architects, engineers, builders, and code officials specifically look for Class A materials when evaluating building products.
