1. Metal roof system must be tested in accordance with Underwriters Laboratories, Inc. (UL) Test Method 580 ‘Tests for Uplift Resistance of Roof Assemblies".
2. Metal roof system must be installed in accordance with UL Construction method [# choose one:
180C (min. 14 gauge purlin, 5’-0" on center max., min. 1" thick rigid insulation and 29 gauge 9/16" deep deck with articulating clips at 5’-0" max.) or
287 (min. 16 gauge purlin, 5’-0" on center max. with low/high articulating clips at 5’-0" on center max. with Light Transmitting Panels) or
308A min. 14 gauge purlin, 5’-0" on center max., min. 1" thick rigid insulation and 22 gauge 1 1/2" deep metal deck with articulating clips at 5'-0" on center max.) or
450 (min. 16 gauge purlin, 5'-0" on center max. with low/high floating/articulating clips with domed Light Transmitting Panels) or
518 (min. 16 gauge purlin, 5'-0 1/4" on center max. with low/high floating/articulating clips with Light Transmitting Panels) or
519 (min. 22 gauge 1 1/2" deck with max 6" rigid insulation with low/high floating/articulating clips 5’-0" on center max.) or
520 (min. 29 gauge 9/16" deck with max 6" rigid insulation with low/high floating/articulating clips
5'-0 1/4" on center max with Light Transmitting Panels)] See the current UL Roofing Materials and Systems Directory for requirements of each Construction Method.
3. Metal roof system must be tested in accordance with ASTM E 1592-95 for negative loading when AISI specifications do not apply. Determine panel bending and clip-to-panel strength by testing in accordance with ASTM E 1592-95 procedures. Capacity for gauge, span or loading other than those tested may be determined by interpolating between test values only.

4. Metal roof system must have details, engineering calculations, computer printouts, and data examined by the ICBO Evaluation Service, Inc. and have been found to comply with the 1997 Uniform Building Code.
5. Metal roof system must qualify for a Class 4 rating when tested in accordance with Underwriters Laboratories, Inc. UL-2218 "Test Standard For Impact Resistance".
6. Metal roof system must meet the air infiltration requirements of ASTM E 1680-95 when tested with a 6.24 PSF pressure differential with resulting air infiltration of 0.0071 cfm/sq ft.
7. Metal roof system must meet the water penetration requirements of ASTM E 1646-95 when tested with a 12.00 PSF pressure differential with no uncontrollable water leakage when five gallons per hour of water is sprayed per square foot of roof area.

# Specifier: Select construction method for paragraph A.1. and applicable building code for paragraph A.2.

1.04 DESIGN REQUIREMENTS

A. Roof Design Loads:

1. Design criteria shall be in accordance with [# choose one: MBMA, SBBCI, UBC, BOCA, ASCE or an applicable national or local building code.]
2. Dead Loads
a. The dead load shall be the weight of the SSSMR system. Collateral loads, such as sprinklers, mechanical and electrical systems, and ceilings shall not be attached to the panels.
3. Live Loads
a. The panels and concealed anchor clips shall be capable of supporting a minimum uniform live load of -20 psf.
4. Roof Snow Loads
a. The design roof snow loads shall be as shown on the contract drawings.
5. Wind Loads
a. The design wind uplift for the roof system shall be as shown on the contract drawings. The design uplift force for each connection assembly shall be that pressure given for the area under consideration, multiplied by the tributary load area of the connection assembly. The safety factor listed below shall be applied to the design force and compared against the ultimate capacity. Prying shall be considered when calculating fastener design loads.
aa. Single fastener in each connection ...3.0
bb. Two or more fasteners in each connection...2.25
