1.1 This specification covers the design, construction, and weatherability of structural standing seam aluminum roof panel systems that resist all superimposed design loads without the benefit of supporting deck or sheathing. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers.

1.2 The objective of this specification is to provide for the overall performance of the standing seam aluminum roof panel system in accordance with 1.1 during its service life in order to provide weather protection, carry the specified design loads, and allow proper access over the roof surface in order to provide periodic maintenance of the equipment by the building owner.

1.3 In addition to structural characteristics, the specifier shall evaluate other characteristics beyond the scope of this specification that affect the final choice of roof construction. These include, but are not limited to, functional, legal, insurance, and economic considerations. See Appendix X1 for the designer's checklist.

1.4 This specification is not intended to exclude products or systems not covered by the referenced documents.

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
