80.7InsulationAny insulation material used between the inner and outer panels shall minimize the entry and/or retention of moisture. Insulation properties shall be unimpaired during the service life of the bus. Any insulation material used inside the engine compartment shall not absorb or retain oils or water and shall be designed to prevent casual damage that may occur during maintenance operations. The combination of inner and outer panels on the sides, roof, wheel wells and ends of the bus, and any material used between these panels, shall provide a thermal insulation sufficient to meet the interior temperature requirements. The bus body shall be thoroughly sealed so that the driver or passengers cannot feel drafts during normal operations with the passenger doors closed. Default
Insulation shall meet the requirements of FMVSS 302. Alternative
All insulation materials shall comply with the Recommended Fire Safety Practices defined in FTA Docket 90-A, dated October 20, 1993. IP 81.Floor coveringThe floor covering shall have a non-skid walking surface that remains effective in all weather conditions. The floor covering, as well as transitions of flooring material to the main floor and to the entrance and exit area, shall be smooth and present no tripping hazards. Seams shall be sealed/welded per manufacturer’s specifications. The standee line shall be approximately 2 in. wide and shall extend across the bus aisle. The color and pattern shall be consistent throughout the floor covering. Alternative Additional requirements Any areas on the floor that are not intended for standees, such as areas “swept” during passenger door operation, shall be clearly and permanently marked. The floor shall be easily cleaned and shall be arranged to minimize debris accumulation. A one-piece center strip shall extend from the vertical wall of the rear settee between the aisle sides of transverse seats to the standee line. If the floor is of a bi-level construction, then the center strip shall be one piece at each level. The covering between the center strip and the wheel housings may be separate pieces. At the rear door, however, a separate strip as wide as the door shall extend from the center strip to the outboard edge of the rear/exit area. The floor under the seats shall be covered with smooth surface flooring material. The floor covering shall closely fit the sidewall in a fully sealed butt joint or extend to the top of the cove.
The lens material shall be translucent polycarbonate. Lenses shall be designed to effectively “mask” the light source. Lenses shall be sealed to inhibit incursion of dust and insects yet be easily removable for service. Access panels shall be provided to allow servicing of components located behind light panels. If necessary, the entire light fixture shall be hinged. 82.1PassengerDefault Automatically dimming first row lights The first light on each side (behind the driver and the front door) is normally turned on only when the front door is opened, in “night run” and “night park.” As soon as the door closes, these lights shall go out. These lights shall be turned on at any time if the toggle switch is in the “on” position. Alternative
To help eliminate windshield reflection on suburban roads where street lighting is at a low level, the second light on each side, when “night run” or “night park” is selected, shall be controlled by the toggle switch; off in “off” and on in “normal.” These lights shall be turned on at any time if the toggle switch is in the “on” position. All interior lighting shall be turned off whenever the transmission selector is in reverse and the engine run switch is in the “on” position. The interior lighting design shall require the approval of the Agency. Default
Fluorescent tubes shall be a maximum 6 ft in length, single-pin, T-12 type (with exceptions granted for extinguishing or dimming fixtures, as noted below). Individual ballast units shall be provided for each light fixture. Ballast shall have a fire-resistant housing, minimum operating frequency of above audible range, reverse polarity protection and integrated circuit breaker/automatic thermal protection. Alternative Enhanced design ballast that minimize arcing and carries a type and CC UL935 certification Default First light modules dim/extinguish when front door is closed When the master switch is in the “run” or “nite/run” mode, the first light module on each side of the coach shall automatically extinguish or dim when the front door is in the closed position and illuminate when the door is opened. This shall be accomplished through the use of a ballast specifically designed for this type application without diminishing the life of the fluorescent tubes. Alternative
No dimming/extinguishing feature of first light modules shall be provided. 82.2Driver areaThe driver’s area shall have a light to provide general illumination, and it shall illuminate the half of the steering wheel nearest the driver to a level of 5 to 10 foot-candles. 82.3Seating areasThe interior lighting system shall provide a minimum 15 foot-candle illumination on a 1 sq ft plane at an angle of 45 degrees from horizontal, centered 33 in. above the floor and 24 in. in front of the seat back at each seat position. Allowable average light level for the rear bench seats shall be 7 foot-candles.
