Are there any details of the testing and manufacturing involved with ShingleVent II-9A Class A Fire Rated?

Flame retardants are added to ShingleVent II-9A to meet UL requirements.

Flame retardants are added to the product to meet UL requirements. ShingleVent II-9A passed both the Spread of Flame test and the Burning Brand test. In the Spread of Flame SVII-9A was installed on a mock roof deck and was subjected to a 1400-degree Fahrenheit flame from a gas burner and a 12 MPH wind for 10 minutes. The test is designed to see if the vent ignites; and, if it does ignite, how far does the flame move down the length of the vent. The maximum distance UL allows the flame to move is 6 feet. SVII-9A did not ignite.  In the Burning Brand test 36 strips of Douglas fir lumber are nailed together and ignited in still air with an igniting temperature in excess of 1600 degrees Fahrenheit. The burning brand is then placed on the most vulnerable position on the test roof deck  in the center right against the external baffle of SVII-9A. While on the roof deck the burning brand is subjected to a 12 MPH wind until the entire burning brand is consumed. To pass this test as well as the Spread of Flame test, UL requires that at no time shall any portion of the roof covering material be blown or fall off the test deck in the form of flaming or glowing brands; the roof deck cannot be exposed by breaking, sliding, cracking or warping of the roof covering; and portions of the roof deck cannot fall away in the form of glowing particles.
