must be placed against a substantially rigid surface.

29.2.1.3.                    The vehicle body must be fixed in position by means of attachments located at or in front of the front wheel centreline and at or to the rear of the rear wheel centreline.

29.2.2.                          Loading Device

29.2.2.1.                    The loading device must consist of a substantially rigid cylinder or semi-cylinder 305 mm ± 5 mm in diameter, with edge radii of 12 mm ± 1 mm.

29.2.2.2.                    The loading device must be of such a length that when set up in accordance with the procedure specified in Clause 29.2.3, one end surface is at least 12 mm beyond the bottom edge of the door window opening, but not of a length that will cause contact with any structure, other than window glass and ventilation window sashes, beyond the bottom edge of the door window opening during the test.

29.2.2.3.                    The loading device must be so constrained that, during the test, it does not rotate nor is it displaced from its direction of travel.

29.2.3.                          Test Method

29.2.3.1.                    The loading device described in clause 29.2.2 must be used to apply the test load.

29.2.3.2.                    The loading device must be located so that:

29.2.3.2.1.              its longitudinal axis is:

29.2.3.2.1.1.       parallel to the vertical longitudinal plane of the vehicle; and

29.2.3.2.1.2.       in the transverse vertical plane of the vehicle which passes through the midpoint of a horizontal line which is drawn across the outer surface of the door 127 mm ± 2 mm above the lowest point of the door when the vehicle is standing on a horizontal surface;

29.2.3.2.2.              an end surface is not closer to the lowest point of the door than the line described in clause 29.2.3.2.1; and

29.2.3.2.3.              the cylindrical face of the device is in contact with the outer surface of the door.

29.2.3.2.4.              The location of the loading device is illustrated in Figure 1.

29.2.3.3.                    The load must be applied to the outer surface of the door in an inboard transverse direction normal to the vehicle's longitudinal centreline.

29.2.3.4.                    The load must be applied such that the travel rate of the loading device does not exceed 13 mm per second until the loading device has been displaced either 460 mm or, provided the peak crush resistance has been satisfied, at least 310 mm. The test must be completed within 120 seconds.

29.2.3.5.                    The variation of displacement of the loading device with applied load must be recorded during the test, either continuously or in increments of not more than 26 mm or 890 N for the total crush distance.

29.3.                                DETERMINATION OF CRUSH RESISTANCE

29.3.1.                          From the results recorded as specified in clause 29.2.3.5, a curve of load versus displacement
