3.1 Introduction: These fire testing standards aim to measure relative fire characteristics of roof coverings with photovoltaic modules and panels mounted above or on the roof covering under simulated fire scenarios which originate outside the building. Under controlled laboratory conditions, the behavioral response of materials, products or assemblies as affected by heat and flame are described. The performances of the roof covering systems are described only under specific conditions. Information is not provided by these tests that are applicable to any scenarios other than the specific conditions experienced during testing. Information is not provided by these tests that are applicable to actual fire situations because of the inherent differences between the classes as it pertains to fire source and fire application; no comparison between the classes exist. Results from tests are applicable to the specifics of the test and the aspect in which the tests were conducted, and are not applicable to similar materials or the results of those materials when used in concert with other materials.

4.0 Test Details: (continued)

4.5 Moisture Content: Moisture content of the lumber and plywood were verified prior to testing. Plywood was less than 8% and the lumber was within 8-10%.

4.6 Equipment Calibration: A Fire Test Apparatus as described in ASTM E108 was used to generate 12 ± 0.5 mph air current and flame temperature of 1400 ±50°F. Air speed and flame temperature of the Fire Test Apparatus were calibrated prior to testing. A gas burner with flame temperature of 1630 ±50°F was used to ignite the brands for testing. See Section 5.1 for more information on equipment calibration.

4.7 Spread of Flame Procedure: After calibration of equipment, a test specimen described in Section 4.1.1 was placed into the steel framed holder for testing at a 5:12 slope and refractory mortar applied at the leading edge of the deck. The fire test apparatus was turned on and the specimen was subjected to continuous flame and air current for duration of 10 minutes. This procedure was repeated for both test decks and observations were documented.

4.8 Burning Brand Procedure: Brands were oven conditioned at 105 to 120°F for a minimum of 24 hours prior to testing. Class A brands consisted of three layers of twelve 1 inch by 1 inch by 12 inch strips of Douglas Fir forming a grid of 12 inch square by 2-1/4 inch thick and weight verified to be within 2000 ±150 grams. The brand was ignited by exposing each 12 inch by 12 inch face for 30 seconds, each 2-1/4 inch by 12 inch face for 45 seconds, and the 12 inch by 12 inch faces again for 30 seconds into the gas burner. Total duration of ignition exposure was 5 minutes. Class B test brands consisted of a grid 6 inches square and approximately 2-1⁄4 inches thick made of dry Douglas Fir lumber free of knots and pitch pockets. Use 18 nominal 1 by 1 by 6 inch strips, dressed on all four faces to 3⁄4 by 3⁄4 inches, and placed in three layers of six strips each with strips spaced 1⁄4 inch. The brands weight was verified to be within 500-650 grams at the time of test. The brand was ignited by exposing each 6 by 6-inch face for 30 seconds, each 2 1⁄4 by 6-inch face for 30 seconds, and each 6 by 6-inch face again for 30 seconds. After the brands were ignited, they were placed onto the test specimen described in Section 4.1.3 of the E108 and Section 31.2.1.2 of the UL 1703 at a 5:12 slope and secured in place with No. 18 soft iron wire. Class A brand were positioned with its upper edge 25.5 inches from the leading edge of the test deck and centered laterally with respect to the vertical joint in the test deck. The brand is to be placed so that the strips in both the upper and lower layers are parallel to the direction of air flow. Class B brand were positioned with its upper edge 24 inches from the leading edge of the test deck and centered laterally with respect to the vertical joint in the test deck. Brands were placed so that the strips in both the upper and lower layers are parallel to the direction of air flow. The testing apparatus without flame but only air current was turned on and the specimen was tested for 90 minutes or until the brand was completely consumed and the exposed and underside surfaces of the test deck did not exhibited signs of combustion. This procedure was repeated for all test decks and observations were documented.
