MARKING

The manufacturer shall mark each product and/or packaging with the manufacturer's name and product trade name. In addition, product and/or packaging must be marked with the Approval Mark of FM Approvals.

Markings denoting Approval by FM Approvals shall by applied by the manufacturer only within and on the premises of manufacturing locations under the FM Approvals Surveillance Audit program.

The manufacturer agrees that use of the FM Approvals name or Approval Mark is subject to the conditions and limitations of the Approval by FM Approvals. Such conditions and limitations must be included in all references to Approval by FM Approvals.

REMARKS

The securement of the roof system must be enhanced at the building corners and perimeter as outlined in FM Global Property Loss Prevention Data Sheet 1-29.

The roof cover must be installed using a roof perimeter flashing system Approved by FM Approvals. See RoofNav.

SURVEILLANCE AUDIT

The manufacturing facilities at the following locations shall be visited on a routine basis. The facility processes and quality control procedures in place have been determined to be satisfactory to manufacture products identical to that tested and Approved. An FM Approved Products/Specification Tested Revision Request Form shall be submitted to FM Approvals for requesting to manufacture products at any additional or alternate manufacturing facilities which are not listed below.

ASC Steel Deck N-32, DGN-32, NF-32 Cellular, or DGNF-32 Cellular is secured to structural supports spaced at the maximum center to center spans shown in the following tables. All above deck component fasteners must be installed in the top flange of the steel roof deck. The insulation boards or thermal barrier, if applicable, installed directly over the steel deck must be cut to fit as needed to provide proper bearing on the top flange of the steel roof deck and secured to the deck as required per proprietary listings.  This deck has an 8 in. (203 mm) rib module.  FM Approved above deck systems are generally targeted to be used with 6 in. (152 mm) rib modules. Therefore, when utilizing an FM Approved mechanically fastened above deck system, select one with fastener spacing greater than 8 in. (203 mm) and reduce this fastener spacing to coincide with placement of the fastener in the deck top flanges (e.g., FM Approved 12 in. (305 mm) spacing is reduced to 8 in. (203 mm) or FM Approved 18 in. (457 mm) spacing is reduced to 16 in. (406 mm) spacing.)

ASC Steel Deck N-32 Acustadek, DGN-32 Acustadek, NF-32 Cellular Acustadek, or DGNF-32 Cellular is secured to structural supports spaced at the maximum center to center spans shown in the following tables. All above deck component fasteners must be installed in the top flange of the steel roof deck. The insulation boards or thermal barrier, if applicable, installed directly over the steel deck must be cut to fit as needed to provide proper bearing on the top flange of the steel roof deck and secured to the deck as required per proprietary listings. This deck has an 8 in. (203 mm) rib module. FM Approved above deck systems are generally targeted to be used with 6 in. (152 mm) rib modules. Therefore, when utilizing an FM Approved mechanically fastened above deck system, select one with fastener spacing greater than 8 in. (203 mm) and reduce this fastener spacing to coincide with placement of the fastener in the deck top flanges (e.g., FM Approved 12 in. (305 mm) spacing is reduced to 8 in. (203 mm) or FM Approved 18 in. (457 mm) spacing is reduced to 16 in. (406 mm) spacing.)

Puddle welds, sized and spaced as noted in the following tables, are fabricated using a minimum weld electrode of strength of 60 ksi (414 MPa) located at bottom ribs and at

supports where deck sides lap. The side laps of interlocking steel decks are secured by button punch, spaced at maximum 36 in. (914 mm) on center. The side laps of all other steel decks are secured using fasteners FM Approved for securing steel deck side laps. Refer to RoofNav product listings for fastener details. The maximum allowable span is the lesser of the deck span shown in the tables below or the maximum span shown in the specified RoofNav assembly. An FM Approved fully or partially adhered roof covering or mechanically attached roof covering with fastener row spacing less than or equal to one-half of the deck span is applied per proprietary listings. Additional requirements, if applicable, are as stated in the following sections. Refer to the use of steel roof decks and fasteners throughout listings for details and limitations. Meets maximum Class 1-90 or per proprietary listings.

ASC Steel Deck N-32, DGN-32, NF-32 Cellular, or DGNF-32 Cellular is secured to structural supports spaced at the maximum center to center spans shown in the following tables. All above deck component fasteners must be installed in the top flange of the steel roof deck. The insulation boards or thermal barrier, if applicable, installed directly over the steel deck must be cut to fit as needed to provide proper bearing on the top flange of the steel roof deck and secured to the deck as required per proprietary listings.  This deck has an 8 in. (203 mm) rib module.  FM Approved above deck systems are generally targeted to be used with 6 in. (152 mm) rib modules. Therefore, when utilizing an FM Approved mechanically fastened above deck system, select one with fastener spacing greater than 8 in. (203 mm) and reduce this fastener spacing to coincide with placement of the fastener in the deck top flanges (e.g., FM Approved 12 in. (305 mm) spacing is reduced to 8 in. (203 mm) or FM Approved 18 in. (457 mm) spacing is reduced to 16 in. (406 mm) spacing.)

ASC Steel Deck N-32 Acustadek, DGN-32 Acustadek, NF-32 Cellular Acustadek, or DGNF-32 Cellular is secured to structural supports spaced at the maximum center to center spans shown in the following tables. All above deck component fasteners must be installed in the top flange of the steel roof deck. The insulation boards or thermal barrier, if applicable, installed directly over the steel deck must be cut to fit as needed to provide proper bearing on the top flange of the steel roof deck and secured to the deck as required per proprietary listings. This deck has an 8 in. (203 mm) rib module. FM Approved above deck systems are generally targeted to be used with 6 in. (152 mm) rib modules. Therefore, when utilizing an FM Approved mechanically fastened above deck system, select one with fastener spacing greater than 8 in. (203 mm) and reduce this fastener spacing to coincide with placement of the fastener in the deck top flanges (e.g., FM Approved 12 in. (305 mm) spacing is reduced to 8 in. (203 mm) or FM Approved 18 in. (457 mm) spacing is reduced to 16 in. (406 mm) spacing.)
