SAE J1100 pdf download.(R) Motor Vehicle Dimensions.
This SAE Recommended Practice defines a set of measurements and standard procedures for vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way.
In addition, some dimensions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected, Also, care should be taken to not confuse design intent measurements with those taken on a physical property.
Unless otherwise specified, all dimensions are measured normal to the three-dimensional reference system see SAE J182), except ground-related dimensions, which are defined normal to ground. All dimensions are taken with the vehicle at curb weight unless otherwise specified.
All dimensions are measured on the base vehicle and do not include Regular Production Options (RPO) or accessory parts, unless otherwise specified.
Although many terms and dimensions use human body parts In their name, they should not be construed as measures that Indicate occupant accommodation, capabilitIes, or comfort

3.2.2 GROSS VEHICLE WEIGHT RATING—The value specified by the vehicle manufacturer as the maximum loaded weight of a single vehicle.
3.2.3 EPA LOAD, EPA WEIGHT—Curb load, pius the weight of all options and accessories which weigh 136 kg (3lb) or more and which are sold on at least 33% of the vehicle line, plus two occupants. Each occupant weighs 68 kg (150 Ib).
3.3 Coordinate Dimension—All points of interest are described as coordinates dimensioned from the intersection of the zero planes in the threedimensional reference system. X, V. Z coordinates are dimensioned to their respective planes. (See Figure 1 See also SAE J182.)

3.5 General Vehicle Reference Points and Definitions
3.5.1 CARGO Fioon—The surface for supporting cargo. If ribs are present, the cargo floor is at the top of the ribs. If the floor is covered, it is the undepressed floor covering surface.
3.5.2 CENTERLINE OF OCcuPANT (C/LO)—The lateral (Y) centerline of an occupant in a given designated seating
position.
3.5.3 COWL PoINT—The highest point on the cowl or hood point on the vehicle centerline (See Figure 2.)
3.5.4 DAVUGHT OPEISNG (DLO)—A line on the exterior glazing surface that defines the minimum unobstructed opening through any glass aperture Opaque coatings, reveals, and garnish moldings are considered obstructions. Opaque coatings, reveals, and garnish moldings adjoining the interior glazing surface are projected normal and outward to the exterior surface. Interior components not adjoining the glass are protected horizontally to the interior glazing surface, then nom’ial and outward to the exterior surface. Exterior components are projected horizontally to the exterior surface.
3.5.5 Dccx POINT—The highest point on the deck lid panel on the vehide centerline. (See Figure 2.)
3.5.6 DEPRESSED FLOOR COVERING—The surface of the floor covenng at a designated point in the vehicle, with a
load applied to the covering as specified by the manufacturer.
3.5.7 DESIONATED SEATING POSITION—Any location intended by the manufacturer to provide seating for a driver or adult passenger while the vehicle is in motion, excluding temporary seating such as folding jump seats. Examples of designated seating positions include driver. 1st row (front seat) outboard passenger, 1St row center passenger, 2nd row outboard passenger, etc.
3.5.8 EVELLIPSE—See SAE J941.
3.5.9 FRoNT OF Dass—A vertical tangent to the foremost predominant surface of the dash panel at the centerline of the driver, disregarding flanges and small localized formations The dash panel is usually the vertical extension of the toe panel.
3.5.10 HEAD POSITION CoNTOuR—See SAE J1052. Dimensions specified in this practice are measured from sections cut through the appropriate 95th percentile head contour. After the head contour is constructed and oriented, sections are cut normal to grid in side view and rear view through the ellipse centroid. The side view section is used for L38, L39. and H41 The rear view section is used for W27, W35 and H35.
3.5.11 NonL TOP OF FRAUE•TRUCK—The longest normal surface of the top flange of the truck frame within the wheel base.
