"83.1 Definition. The steering control system is defined as the basic steering mechanism in combination with its associated horn actuating mechanism, trim hardware, etc., and includes any portion of the steering column assembly that may contain an energy absorber for the purpose of dissipating energy upon impact.

"83.2 The steering control assembly shall be constructed so that when it is impacted at a relative velocity of 22 feet per second with a torso shaped body block as shown in Agure 1 [not shown in RECORD], weighing 75-80 pounds, and having a spring rate load of 600-800 pounds per inch, the force developed during collapse of the system shall not exceed 2,500 pounds. The spring rate is determined by loading the chest of the torso 14225 shaped body block with a 4-inch wide flat

contact surface so that it is 90 degrees to the longitudinal axis of the body block, parallel to the backing plate and within 15 to 20 inches from the top of the head form. The load is measured when the flat contact surface has moved down 1⁄21⁄2 inch, and the spring rate is determined by doubling this load figure.

"88.2.1 When the steering wheel is the principal energy absorbing element, the load cell recording device shall be equivalent to the type shown in igure 2 and shall be mounted either directly behind the wheel or in the frontal surface of the body block, with its axis of primary sensitivity in the direction of body block travel at the time of impact. The steering wheel shall be mounted to the load cell by means of an appropriate nose piece at the same angle as it is to be installed in the vehicle.

"83.2.2 When a component or components other than the steering wheel, such as the steering column, is the principal energy absorbing element or contributes substantially to the absorption of energy, the load cell shall be located between the steering wheel and the remainder of the energy absorbing system, preferably immediately under the

wheel, or in the forward, impacting surface of the body block.

"83.3 Other testing methods, such as high capacity acceleration facilities and anthropometric dummies, giving equivalent results, may be utilized in lieu of methods defined in $3.2, S3.2.1, and S3.2.2.

"83.4 The steering control assembly shall be so designed that when the front structure of the automotive vehicle collapses during the SAE J850 barrier collision test, or equivalent at 30 miles per hour, the upper end of the steering control system shall not be displaced rearward, relative to an undisturbed point to the rear of the steering wheel position, more than 5 inches. "63.4.1

The rearward displacement of the steering control assembly shall be determined under dynamic conditions during the barrier collision or equivalent test.
