[BS] 1404.5.1 Aluminum Siding
Aluminum siding shall conform to the requirements of AAMA 1402. AAMA 1402 shall be modified to read as follows:
3.0 SIDING SPECIFICATIONS.
126.96.36.199 Static Pressure Test.
188.8.131.52.1 All siding products shall be capable of resisting the design pressures specified for walls for components and cladding loads in accordance with Section 1609.1.1. To verify that the soffit will perform under these conditions, it shall be tested in the maximum unsupported length for which the manufacturer seeks conformance when tested in accordance with Test Method #1, "Standard for Testing of Aluminum Siding/Fastener and Windload Resistance."
The static test pressure shall be as required to demonstrate compliance with the provisions of Section 1609.1.
184.108.40.206.2 For applications where the effective design pressure as specified in Section 1609.1.1 is greater than 1040 Pa (21.7 psf) [e.g., wind zone areas greater than 36 m/s (80 mph) or elevations above 33 feet (10 m) the product shall be tested in accordance with Test Method #1 under a static test pressure determined by the formula:
PT = Static Test Pressure [Pa (psf)]
DPp = Design Pressure [Pa (psf)]
1.5 = Safety Factor
Appendix A1.0 Windload Criteria is deleted in its entirety.
