Specifications include, but are not limited to: Removed Components All components removed from Department truck chassis and not re-installed or directly re-used on a Department chassis, must be shipped to the Department Central Repair Shop in Ames, IA. Examples would include fuel tanks, brackets, taillights and any or all other components. Electronic Shielding – RFI Protection Trucks will have 2-way, land mobile radio transceivers installed by Department personnel. Transceivers will operate in the high band at 700/800 (150 to 174 MHz and 700/800 MHz). Antennas will be mounted on the roof or highest plane surface of the truck. All electronic circuits, including but not limited to ignition, AM/FM radios, computers, emission controls, alternative fuel electronic controls, regulators and/or any equipment controls must be designed to prevent interference that could affect the Department transceivers. Vehicle’s electronic equipment must also be unaffected by the radio frequency energy generated by the (up to 125-Watt output) transmitter of the installed transceivers. Electrical system must be designed so that the vehicle must not degrade the 2-way radio receiver performance. The effective sensitivity of the BHF or 700/800 MHz FM receiver must not require more than 0.5 microvolts (-111 dbm) to produce 12db or greater SINAD. Effective sensitivity must not exceed 0.5 microvolts for all modes of operation which must include but not be limited to engine off, engine on (from idle to full throttle) and all vehicle systems. Truck may be tested by the Department upon delivery and must meet these RFI requirements. The Department currently utilizes multiple frequencies from 150-163 MHz and 700/800 MHz and will test RFI in these bandwidths. Paint and Coatings All equipment must be thoroughly cleaned and completely coated with a high quality, corrosion resistant finish. Truck cab/chassis: Truck cab must be painted with a 2-step, factory basecoat/clear-coat process. Frame and undercarriage must be completely painted with a high quality, black single step finish to provide maximum corrosion protection. Dealer may be required to extensively touch-up factory undercarriage paint if it is deemed inadequate to provide good corrosion protection. NO bare ferrous metal components must be visible on the chassis, or any components, OEM or outfitter installed. Outfitter installed equipment: All manufactured equipment attached to the Department chassis must be sand/media blasted, or a phosphate solution applied to remove all mill scale, oils, dirt, rust, shipping primer and/or other contaminants from surfaces. This means any component that is subject to corrosion. Phosphate coatings are allowed on All outfitter installed equipment must be powder coated. Powder coating is required because of the durability of this product. The Department requires that any component that can be powder coated should come with that product applied. All items must be individually powder coated before assembly. If a component cannot be powder-coated, it must be completely painted, and rust proofed. Visible exterior surfaces must be painted to match the truck cab. Visible body parts must be painted with a premium quality polyurethane finish. All visible finishes must be smooth, shiny and free of runs, overspray and/or other defects with a minimum finished application thickness of 4 mils, dry film build. Powder-coat, paints and primers used must be 100% lead and chromate free. MSDS on products used must be made immediately available upon request. Regardless of finish type, these color requirements must apply: ORANGE REQUIREMENT – Standard Iowa Department of Transportation orange color is “OMAHA ORANGE”. Known acceptable colors are International 0311 and Freightliner N6389EA. Other manufacturer’s orange paint color must be approved. All components used in the fabrication of a Department truck that are required to be coated orange must be color matched to the OEM chassis cab color. BLACK REQUIREMENT – All components used in the fabrication of a Department truck, that are required to be coated black, must have a high quality, black finish. After installation, all installed components must be inspected and touched-up to provide a uniform finish. Underside of frame must be inspected for bare metal and appropriate corrective action must be taken to provide maximum corrosion protection. NO bare ferrous metal must be visible on the chassis or any installed equipment.
