This Regulation applies to motor vehicles of categories M1 and N1
   (1).

1

However, vehicles of category N1 where the driver’s position ‘R-point’ is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1 100 mm, are exempted from the requirements of this Regulation.

1

This Regulation does not apply to vehicles of category M1 above 2 500 kg maximum mass and which are derived from N1 category vehicles, and where the driver’s position ‘R-point’ is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1 100 mm; for these vehicle categories Contracting Parties may continue to apply the requirements already in force for that purpose at the time of acceding to this Regulation.

2.   DEFINITIONS

When performing measurements as described in this Part, the vehicle should be positioned in its normal ride attitude.

If the vehicle is fitted with a badge, mascot or other structure, which would bend back or retract under an applied load of maximum 100 N, then this load shall be applied before and/or while these measurements are taken.

Any vehicle component which could change shape or position, other than suspension components or active devices to protect pedestrians, shall be set to their stowed position.

For the purposes of this Regulation:

| 2.1. | ‘Adult headform test area’ is an area on the outer surfaces of the front structure. The area is bounded:






  (a) | In the front, by a wrap around distance (WAD) of 1 700 or a line 82,5 mm rearward of the bonnet leading edge reference line, whichever is most rearward at a given lateral position; |
| --- | --- | --- |

2.1.

‘Adult headform test area’ is an area on the outer surfaces of the front structure. The area is bounded:

(a)

In the front, by a wrap around distance (WAD) of 1 700 or a line 82,5 mm rearward of the bonnet leading edge reference line, whichever is most rearward at a given lateral position;

| (b) | At the rear, by a WAD 2 100 or a line 82,5 mm forward of the bonnet rear reference line, whichever is most forward at a given lateral position, and |
| --- | --- |

(b)

At the rear, by a WAD 2 100 or a line 82,5 mm forward of the bonnet rear reference line, whichever is most forward at a given lateral position, and

| (c) | At each side, by a line 82,5 mm inside the side reference line. |
| --- | --- |

(c)

At each side, by a line 82,5 mm inside the side reference line.

The distance of 82,5 mm is to be set with a flexible tape held tautly along the outer surface of the vehicle.

| 2.2. | ‘Assessment Interval (AI)’ of the flexible lower legform impactor is defined and limited by the time of first contact of the flexible lower legform impactor with the vehicle and the timing of the last zero crossing of all femur and tibia segments after their first local maximum subsequent to any marginal value of 15 Nm, within their particular common zero crossing phases. The AI is identical for all bone segments and knee ligaments. In case of any bone segment not having a zero crossing during the common zero crossing phases, the time history curves for all bone segments are shifted downwards until all bending moments are crossing zero. The downwards shift is to be applied for the determination of the AI only. |

| 2.5. | ‘Bonnet leading edge’ means the edge of the front upper outer structure of the vehicle, including the bonnet and wings, the upper and side members of the headlight surrounds and any other attachments. The reference line identifying the position of the bonnet leading edge is defined by its height above the ground reference plane and by the horizontal distance separating it from the bumper (bumper lead). |

2.5.

‘Bonnet leading edge’ means the edge of the front upper outer structure of the vehicle, including the bonnet and wings, the upper and side members of the headlight surrounds and any other attachments.

  For vehicles having the bonnet top surface inclined at 50°, so that the straight edge makes a continuous contact or multiple contacts rather than a point contact, the reference line is determined with the straight edge inclined rearwards at an angle of 40° from the vertical.
  For vehicles of such shape that the bottom end of the straight edge makes first contact, then that contact is taken to be the bonnet leading edge reference line, at that lateral position.
  For vehicles of such shape that the top end of the straight edge makes first contact with the vehicle, then the geometric trace of 1 000 mm wrap around distance will be used as the bonnet leading edge reference line at that lateral position.
  The top edge of the bumper shall also be regarded as the bonnet leading edge for the purposes of this Regulation, if it is contacted by the straight edge during this procedure. |

The wiper blades and arms are removed during this process.
  Where the bonnet rear reference line and the side reference line do not intersect, the bonnet rear reference line should be extended and/or modified using a semi-circular template, of radius 100 mm. The template should be made of a thin flexible sheet material that easily bends to a single curvature in any direction. The template should, preferably, resist double or complex curvature where this could result in wrinkling. The recommended material is a foam backed thin plastic sheet to allow the template to ‘grip’ the surface of the vehicle.
  The template should be marked up with four points ‘A’ through ‘D’, as shown in Figure 3, while the template is on a flat surface.
  The template should be placed on the vehicle with Corners ‘A’ and ‘B’ coincident with the side reference line. Ensuring these two corners remain coincident with the side reference line, the template should be slid progressively rearwards until the arc of the template makes first contact with the bonnet rear reference line. Throughout the process, the template should be curved to follow, as closely as possible, the outer contour of the vehicle’s bonnet top, without wrinkling or folding of the template. If the contact between the template and bonnet rear reference line is tangential and the point of tangency lies outside the arc scribed by points ‘C’ and ‘D’, then the bonnet rear reference line is extended and/or modified to follow the circumferential arc of the template to meet the bonnet side reference line, as shown in Figure 4.
  If the template cannot make simultaneous contact with the bonnet side reference line at points ‘A’ and ‘B’ and tangentially with the bonnet rear reference line, or the point at which the bonnet rear reference line and template touch lies within the arc scribed by points ‘C’ and ‘D’, then additional templates should be used where the radii are increased progressively in increments of 20 mm, until all the above criteria are met. |

3.3.1.

| 3.3.2. | The headform impactor shall be dropped from the specified height by means that ensure instant release onto a rigidly supported flat horizontal steel plate, over 50 mm thick and over 300 mm × 300 mm square which has a clean dry surface and a surface finish of between 0,2 and 2,0 micrometer. |

3.3.2.

| 3.3.3. | The headform impactor shall be dropped with the rear face of the impactor at the test angle specified in Annex 5, paragraph 4.7 for the child headform impactor and in Annex 5, paragraph 5.7 for the adult headform impactor with respect to the vertical as shown in Figure 9 below. The suspension of the headform impactor shall be such that it does not rotate during the fall. |

3.3.3.

| 3.3.4. | The drop test shall be performed three times, with the headform impactor rotated 120° around its symmetrical axis after each test.
