<br />Tech Brief
<br />Class A Fire Rating
<br />Background
<br />All roofing products are tested and
<br />classified for their ability to resist fire.
<br />Recently, these fire resistance standards
<br />were expanded to include solar equipment
<br />as part of the roof system. Specifically, this
<br />requires the modules, mounting hardware
<br />and roof covering to be tested together as
<br />a system to ensure they achieve the same
<br />fire rating as the original roof covering.
<br />These new requirements are being adopted
<br />throughout the country in 2016.
<br />IronRidge Certification
<br />IronRidge was the first company to
<br />receive a Class A Fire Rating—the highest
<br />possible rating—from Intertek Group plc., a
<br />Nationally Recognized Testing Laboratory.
<br />IronRidge Flush Mount and Tilt Mount
<br />Systems were tested on sloped and flat
<br />roofs in accordance with the new UL 1703
<br />& UL 2703 test standards. The testing
<br />evaluated the system’s ability to resist
<br />flame spread, burning material and
<br />structural damage to the roof.
<br />Refer to the table below to determine the
<br />requirements for achieving a Class A Fire
<br />Rating on your next project.
<br />Test Setup
<br />Solar Modules
<br />Solar modules are given a Type
<br />classification based on their
<br />materials and construction.
<br />Mounting System
<br />Mounting is tested as part of a
<br />system that includes type-tested
<br />modules and fire-rated roof covering.
<br />Roof Covering
<br />Roof covering products are given a
<br />Fire Class Rating of A, B or C based
<br />on their tested fire resistance.
<br />A burning wooden block is placed on module as a fan blows at 12 mph.
<br />Flame cannot be seen on underside of roof within 90 minutes.
<br />Burning Brand Test
<br />Flame at southern edge of roof is aimed up the roof as a fan blows at 12
<br />mph. The flame cannot spread 6 feet or more in 10 minutes.
