EXPLANATORY NOTES

Paragraph 2.3.

The reference zone is outlined without rear view mirror. The energy-dissipation test is accomplished without the rear view mirror. The pendulum shall not impact the mirror mounting.

Paragraphs 2.3. and 2.3.1.

The exempted area behind the steering wheel as defined by these paragraphs is also valid for the head impact area of the front passengers.

In the case of adjustable steering wheels the zone finally exempted is reduced to the common area of the exempted zones for each of the driving positions which the steering wheel may assume.

In the case where it is possible to choose between various steering wheels the exempted zone is determined by the use of the least favourable steering wheel having the smallest diameter.

Paragraph 2.4.

The level of the instrument panel extends over the entire width of the passenger compartment and is defined by the rearmost points of contact of a vertical line with the surface of the instrument panel when the line is moved across the width of the vehicle. Where two or more points of contact occur simultaneously, the lower point of contact shall be used to establish the level of the instrument panel. In the case of consoles, if it is not possible to determine the level of the instrument panel by reference to the points of contact of a vertical line the level of the instrument panel shall be where a horizontal line 25.4 mm above the "H" point of the front seats intersects the console.

Paragraph 2.5.

At the vehicle sides the roof shall commence at the upper edge of the door aperture. In the normal case, the lateral roof limits will be represented by the contours formed by the bottom edge (lateral view) of the remaining body when the door has been opened. In the case of windows, the lateral limitation of the roof will be the continuous transparent line (penetration point of the lateral windowpanes). At the posts, the lateral roof limitation will pass through the connecting line between the transparent lines. The definition of paragraph 2.5. is also valid for any opening for the roof, in the closed position, of a vehicle as defined in paragraphs 2.7. or 2.8.  For measuring purposes, downward facing flanges shall be ignored. These will be considered as forming part of the vehicle sidewall.
