The following procedures apply to determining compliance with paragraph S3: (a) Place side windows in their uppermost position and all doors in locked position. Place the sill of the side of the vehicle opposite to the side being tested against a rigid unyielding vertical surface. Fix the vehicle rigidly in position by means of tiedown attachments located at or forward of the front wheel centerline and at or rearward of the rear wheel centerline. (b) Prepare a loading device consisting of a rigid steel cylinder or semicylinder 305 mm (12 inches) in diameter with an edge radius of 13 mm ( (1) For doors with windows, the top surface of the loading device is at least 13 mm ( (2) For doors without windows, the top surface of the loading device is at the same height above the ground as when the loading device is positioned in accordance with paragraph (b)(1) of this section for purposes of testing a front door with windows on the same vehicle. (c) Locate the loading device as shown in Figure 1 (side view) of this section so that— (1) Its longitudinal axis is vertical. (2) Except as provided in paragraphs (c)(2) (i) and (ii) of this section, its longitudinal axis is laterally opposite the midpoint of a horizontal line drawn across the outer surface of the door 127 mm (5 inches) above the lowest point of the door, exclusive of any decorative or protective molding that is not permanently affixed to the door panel. (i) For contoured doors on trucks, buses, and multipurpose passenger vehicles with a GVWR of 4,545 kg (10,000 pounds) or less, if the length of the horizontal line specified in (c)(2) is not equal to or greater than 559 mm (22 inches), the line is moved vertically up the side of the door to the point at which the line is 559 mm (22 inches) long. The longitudinal axis of the loading device is then located laterally opposite the midpoint of that line. (ii) For double side doors on trucks, buses, and multipurpose passenger vehicles with a GVWR of 4,545 kg (10,000 pounds) or less, its longitudinal axis is laterally opposite the midpoint of a horizontal line drawn across the outer surface of the double door span, 127 mm (5 inches) above the lowest point on the doors, exclusive of any decorative or protective molding that is not permanently affixed to the door panel. (3) Except as provided in paragraphs (c)(3) (i) and (ii) of this section, its bottom surface is in the same horizontal plane as the horizontal line drawn across the outer surface of the door 127 mm (5 inches) above the lowest point of the door, exclusive of any decorative or protective molding that is not permanently affixed to the door panel. (i) For contoured doors on trucks, buses, and multipurpose passenger vehicles with a GVWR of 4,545 kg (10,000 pounds) or less, its bottom surface is in the lowest horizontal plane such that every point on the lateral projection of the bottom surface of the device on the door is at least 127 mm (5 inches), horizontally and vertically, from any edge of the door panel, exclusive of any decorative or protective molding that is not permanently affixed to the door panel. (ii) For double side doors, its bottom surface is in the same horizontal plane as a horizontal line drawn across the outer surface of the double door span, 127 mm (5 inches) above the lowest point of the doors, exclusive of any decorative or protective molding that is not permanently affixed to the door panel. (d) Using the loading device, apply a load to the outer surface of the door in an inboard direction normal to a vertical plane along the vehicle's longitudinal centerline. Apply the load continuously such that the loading device travel rate does not exceed one-half inch per second until the loading device travels 18 inches. Guide the loading device to prevent it from being rotated or displaced from its direction of travel. The test must be completed within 120 seconds. (e) Record applied load versus displacement of the loading device, either continuously or in increments of not more than 1 inch or 200 pounds for the entire crush distance of 18 inches. (f) Determine the initial crush resistance, intermediate crush resistance, and peak crush resistance as follows: (1) From the results recorded in paragraph (e) of this section, plot a curve of load versus displacement and obtain the integral of the applied load with respect to the crush distances specified in paragraphs (f) (2) and (3) of this section. These quantities, expressed in inch-pounds and divided by the specified crush distances, represent the average forces in pounds required to deflect the door those distances. (2) The initial crush resistance is the average force required to deform the door over the initial 6 inches of crush. (3) The intermediate crush resistance is the average force required to deform the door over the initial 12 inches of crush.

Each vehicle is loaded to its unloaded vehicle weight, plus 300 pounds or its rated cargo and luggage capacity (whichever is less), secured in the luggage or load-carrying area, plus the weight of the necessary anthropomorphic test dummies. Any added test equipment is located away from impact areas in secure places in the vehicle. The vehicle's fuel system is filled in accordance with the following procedure. With the test vehicle on a level surface, pump the fuel from the vehicle's fuel tank and then operate the engine until it stops. Then, add Stoddard solvent to the test vehicle's fuel tank in an amount which is equal to not less than 92 percent and not more than 94 percent of the fuel tank's usable capacity stated by the vehicle's manufacturer. In addition, add the amount of Stoddard solvent needed to fill the entire fuel system from the fuel tank through the engine's induction system. S6.2 Vehicle test attitude. Determine the distance between a level surface and a standard reference point on the test vehicle's body, directly above each wheel opening, when the vehicle is in its “as delivered” condition. The “as delivered” condition is the vehicle as received at the test site, filled to 100 percent of all fluid capacities and with all tires inflated to the manufacturer's specifications listed on the vehicle's tire placard. Determine the distance between the same level surface and the same standard reference points in the vehicle's “fully loaded condition.” The “fully loaded condition” is the test vehicle loaded in accordance with S6.1. The load placed in the cargo area is centered over the longitudinal centerline of the vehicle. The pretest vehicle attitude is equal to either the as delivered or fully loaded attitude or between the as delivered attitude and the fully loaded attitude. S6.3 Adjustable seats. Adjustable seats are placed in the adjustment position midway between the forward most and rearmost positions, and if separately adjustable in a vertical direction, are at the lowest position. If an adjustment position does not exist midway between the forwardmost and rearmost positions, the closest adjustment position to the rear of the midpoint is used. S6.4 Adjustable seat back placement. Place adjustable seat backs in the manufacturer's nominal design riding position in the manner specified by the manufacturer. If the position is not specified, set the seat back at the first detent rearward of 25° from the vertical. Place each adjustable head restraint in its highest adjustment position. Position adjustable lumbar supports so that they are set in their released, i.e., full back position. S6.5 Adjustable steering wheels. Adjustable steering controls are adjusted so that the steering wheel hub is at the geometric center of the locus it describes when it is moved through its full range of driving positions. S6.6 Windows. Movable vehicle windows and vents are placed in the fully closed position on the struck side of the vehicle. S6.7 Convertible tops. Convertibles and open-body type vehicles have the top, if any, in place in the closed passenger compartment configuration. S6.8 Doors. Doors, including any rear hatchback or tailgate, are fully closed and latched but not locked. S6.9 Transmission and brake engagement. For a vehicle equipped with a manual transmission, the transmission is placed in second gear. For a vehicle equipped with an automatic transmission, the transmission is placed in neutral. For all vehicles, the parking brake is engaged. S6.10 Moving deformable barrier. The moving deformable barrier conforms to the dimensions shown in Figure 2 and specified in part 587. S6.11 Impact reference line. Place a vertical reference line at the location described below on the side of the vehicle that will be struck by the moving deformable barrier: S6.11.1 Passenger cars. (a) For vehicles with a wheelbase of 114 inches or less, 37 inches forward of the center of the vehicle's wheelbase. (b) For vehicles with a wheelbase greater than 114 inches, 20 inches rearward of the centerline of the vehicle's front axle. S6.11.2 Multipurpose passenger vehicles, trucks and buses. (a) For vehicles with a wheelbase of 98 inches or less, 12 inches rearward of the centerline of the vehicle's front axle, except as otherwise specified in paragraph (d) of this section. (b) For vehicles with a wheelbase of greater than 98 inches but not greater than 114 inches, 37 inches forward of the center of the vehicle's wheelbase, except as otherwise specified in paragraph (d) of this section. (c) For vehicles with a wheelbase greater than 114 inches, 20 inches rearward of the centerline of the vehicle's front axle, except as otherwise specified in paragraph (d) of this section. (d) At the manufacturer's option, for different wheelbase versions of the same model vehicle, the impact reference line may be located by the following: (1) Select the shortest wheelbase vehicle of the different wheelbase versions of the same model and locate on it the impact reference line at the location described in (a), (b) or (c) of this section, as appropriate; (2) Measure the distance between the seating reference point (SgRP) and the impact reference line; (3) Maintain the same distance between the SgRP and the impact reference line for the version being tested as that between the SgRP and the impact reference line for the shortest wheelbase version of the model. (e) For the compliance test, the impact reference line will be located using the procedure used by the manufacturer as the basis for its certification of compliance with the requirements of this standard. If the manufacturer did not use any of the procedures in this section, or does not specify a procedure when asked by the agency, the agency may locate the impact reference line using either procedure. S6.12 Impact configuration. The test vehicle (vehicle A in Figure 3) is stationary. The line of forward motion of the moving deformable barrier (vehicle B in Figure 3) forms an angle of 63 degrees with the centerline of the test vehicle. The longitudinal centerline of the moving deformable barrier is perpendicular to the longitudinal centerline of the test vehicle when the barrier strikes the test vehicle. In a test in which the test vehicle is to be struck on its left (right) side: All wheels of the moving deformable barrier are positioned at an angle of 27 ±1 degrees to the right (left) of the centerline of the moving deformable barrier; and the left (right) forward edge of the moving deformable barrier is aligned so that a longitudinal plane tangent to that side passes through the impact reference line within a tolerance of ±2 inches when the barrier strikes the test vehicle. S6.13 Anthropomorphic test dummies. S6.13.1 The anthropomorphic test dummies used for evaluation of a vehicle's side impact protection conform to the requirements of subpart F of part 572 of this chapter. In a test in which the test vehicle is to be struck on its left side, each dummy is to be configured and instrumented to be struck on its left side, in accordance with subpart F of part 572. In a test in which the test vehicle is to be struck on its right side, each dummy is to be configured and instrumented to be struck on its right side, in accordance with subpart F of part 572. S6.13.2 Each part 572, subpart F test dummy specified is clothed in formfitting cotton stretch garments with short sleeves and midcalf length pants.

Each test dummy is restrained using all available belt systems in all seating positions where such belt restraints are provided. In addition, any folding armrest is retracted. S7.1 Torso. For a test dummy in any seating position, hold the dummy's head in place and push laterally on the non-impacted side of the upper torso in a single stroke with a force of 15–20 lb. towards the impacted side. S7.1.1 For a test dummy in the driver position. (a) For a bench seat. The upper torso of the test dummy rests against the seat back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and passes through the center of the steering wheel. (b) For a bucket seat. The upper torso of the test dummy rests against the seat back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and coincides with the longitudinal centerline of the bucket seat. S7.1.2 For a test dummy in the front outboard passenger position. (a) For a bench seat. The upper torso of the test dummy rests against the seat back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and the same distance from the vehicle's longitudinal centerline as would be the midsagittal plane of a test dummy positioned in the driver position under S7.1.1. (b) For a bucket seat. The upper torso of the test dummy rests against the seat back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and coincides with the longitudinal centerline of the bucket seat.

The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and, if possible, the same distance from the vehicle's longitudinal centerline as the midsagittal plane of a test dummy positioned in the driver position under S7.1.1. If it is not possible to position the test dummy so that its midsagittal plane is parallel to the vehicle longitudinal centerline and is at this distance from the vehicle's longitudinal centerline, the test dummy is positioned so that some portion of the test dummy just touches, at or above the seat level, the side surface of the vehicle, such as the upper quarter panel, an armrest, or any interior trim (i.e., either the broad trim panel surface or a smaller, localized trim feature). (b) For a bucket or contoured seat. The upper torso of the test dummy rests against the seat back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle's longitudinal centerline, and coincides with the longitudinal centerline of the bucket or contoured seat. S7.2 Pelvis. S7.2.1 H-point. The H-points of each test dummy coincide within S7.2.2 Pelvic angle. As determined using the pelvic angle gauge (GM drawing 78051–532 incorporated by reference in part 572, subpart E of this chapter) which is inserted into the H-point gauging hole of the dummy, the angle of the plane of the surface on the lumbar-pelvic adaptor on which the lumbar spine attaches is 23 to 25 degrees from the horizontal, sloping upward toward the front of the vehicle. S7.3 Legs. S7.3.1 For a test dummy in the driver position. The upper legs of each test dummy rest against the seat cushion to the extent permitted by placement of the feet. The left knee of the dummy is positioned such that the distance from the outer surface of the knee pivot bolt to the dummy's midsagittal plane is six inches. To the extent practicable, the left leg of the test dummy is in a vertical longitudinal plane. S7.3.2 For a test dummy in the outboard passenger positions. The upper legs of each test dummy rest against the seat cushion to the extent permitted by placement of the feet. The initial distance between the outboard knee clevis flange surfaces is 11.5 inches. To the extent practicable, both legs of the test dummies in outboard passenger positions are in vertical longitudinal planes. Final adjustment to accommodate placement of feet in accordance with S7.4 for various passenger compartment configurations is permitted. S7.4 Feet. S7.4.1 For a test dummy in the driver position. The right foot of the test dummy rests on the undepressed accelerator with the heel resting as far forward as possible on the floorpan. The left foot is set perpendicular to the lower leg with the heel resting on the floorpan in the same lateral line as the right heel. S7.4.2 For a test dummy in the front outboard passenger position. The feet of the test dummy are placed on the vehicle's toeboard with the heels resting on the floorpan as close as possible to the intersection of the toeboard and floorpan. If the feet cannot be placed flat on the toeboard, they are set perpendicular to the lower legs and placed as far forward as possible so that the heels rest on the floorpan. S7.4.3 For a test dummy in either of the rear outboard passenger positions. The feet of the test dummy are placed flat on the floorpan and beneath the front seat as far as possible without front seat interference. If necessary, the distance between the knees can be changed in order to place the feet beneath the seat. S8. Phase-in of dynamic test and performance requirements.
