The language included in the 2012 IBC requires that the combination of roof mounted solar modules and racking components is to be considered a system (IBC Section 1509.7.2). Additionally, it requires that this system shall meet or exceed the ﬁre classiﬁca- tion of the roof assembly. The objective is to ensure that the PV system does not adversely aﬀect the ﬁre rating of the roof. Roof sur- face ﬁre ratings are classiﬁed either A, B, or C; Class A being the most resistant to the spread of ﬂame. Since the physical characteristics of the PV module (material, thickness of glass, etc) also potentially af- fect how a ﬁre will act, modules are now tested and assigned a “type” based upon these characteristics and spread of ﬂame test results. There are 15 total module types, Types 1, 2 and 3 represent dif- ferences in the module composition and Types 4 – 15 are the same module compositions as Types 1 – 3 with diﬀering ﬁre test performance. SnapNrack Series 100 has been Certiﬁed for a Class A ﬁre rating with Type 1 and Type 2 modules, in accordance with the standards set forth in UL1703/2703 and IBC 2012. In or- der to maintain this classiﬁcation, the SnapNrack mounting system must be installed per the UL-approved Installation Manual. Because the test was conducted with the modules at 5 inches from the roof surface (worst case scenario), there is no restriction to the standoﬀ height.
