One component of the fire test for roof coverings is the “brand” test. “A”, “B” and “C” brands are shown in this photograph. The “A” brand is 12" x 12", the “B” brand is 6" by 6". The “C” brand is about the size of an ice cube. The “A” and “B” brands are constructed using a three-layer construction (the middle layer is perpendicular to the top and bottom layer. Each “stick” is 3/4" x 3/4". The other two parts of the fire test for roof coverings are 1) flame spread and 2) potential for the roofing to generate embers. The covering must pass all three parts.
