ACCEPTANCE CRITERIA FOR PROPRIETARY ATTACHMENT SYSTEMS OF PHOTOVOLTAIC (PV) ARRAYS TO ROOF ASSEMBLIES (AC467) Page 4 of 4 specimens in accordance with Section 8.6 of ASTM D4434-15 (Section 8.5 of ASTM D4434-12). Heat aging shall comply with Section 8.7 of ASTM D4434-15 (Section 8.6 of ASTM D4434-12). The seam of the test specimens must be made by heat-welding the PVC material in a manner representative of the roof membrane manufacturer’s recommended practices. 3.4 Seismic Installation: In Seismic Design Categories D, E or F, the attachment system must be connected to the roof deck with the use of fasteners, such as screws, bolts, etc. When using tie-downs to resist seismic loads in Seismic Design Category D, E or F, the load path from the tie-down to the roof deck must also include a mechanical connection such as a screw or bolt. 3.5 Special Inspection: Periodic special inspections are required for the installation of the proprietary attachment system onto the roof assemblies as mandated by the provisions of the IBC Section 1705.12 (2018, 2015 and 2012 IBC Section 1705.11, 2009 IBC Section 1705.4) for wind resistance and in accordance with IBC Section 1705.1.1 (2009 IBC 1704.15) in Seismic Design Categories D, E or F. The duties of the special inspector are to verify that the fasteners are connected to the roof deck and that the tie-downs and caps are properly heat-welded to the roof membrane. 4.0 QUALITY CONTROL 4.1 Quality documentation complying with the ICC-ES Acceptance Criteria for Quality Documentation (AC10) shall be submitted. 4.2 A qualifying inspection shall be conducted at each manufacturing facility in accordance with the requirements of the ICC-ES Acceptance Criteria for Inspections and Inspection Agencies (AC304). 4.3 An annual inspection shall be conducted in accordance with AC304 at each facility manufacturing the proprietary attachment system components. 5.0 EVALUATION REPORT The evaluation report shall contain the following information: • Basic information required by Section 2.1, including product description, installation procedures, packaging and identification. • Details on the applicable types of roof covering systems. The roof covering type and manufacturer must be identified. • Allowable load capacities for the attachment system for the uplift and lateral load directions. • Seismic installation limitations. • A statement indicating that the methods of mounting the PV rack structure to the roof must be designed by a registered design professional and must not exceed the allowable load capacities in the evaluation report. • A statement indicating that the roof assembly, including the roof deck must be designed by a registered design professional to resist the applied loads coming from the proprietary attachment system. • A statement of special inspection in accordance with Section 3.5 of this criteria. • A statement indicating that electrical safety, grounding provisions and grounding continuity are outside the scope of the evaluation report. • A statement indicating that the proprietary attachment system must be flashed in accordance with accepted recommended practices by the roof membrane manufacturer. • A statement indicating that the location of the PV array on a roof shall be established by the local jurisdiction, based on consideration of access by fire personnel, roof vents, and other roof features. • A statement indicating that the PV mounting system must be installed in accordance with the installation instructions of the PV modules and PV mounting system manufacturer. • A statement indicating that PV modules connected to the PV mounting system must comply with the applicable sections in Chapter 15 of the IBC. • A statement indicating that installation of PV modules must comply with 2021 IFC Section 1205 (2018 IFC Section 1204, 2015 and 2012 IFC Section 605.11). ∎ Figure 1—Components of Proprietary Attachment System Using Tie-down and Cap 1441 W 17th St - 101115926 & 20180369 11/16/2023
