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.

Paragraph 2.7.

A non-removable rear window is understood to be a rigid structural element.

Cars with non-removable rear windows of rigid material are considered to be cars with opening roofs as defined under paragraph 2. 8.

Paragraph 2.18.

In case of a gap between the edge of a rigid material and the panel, this edge shall be rounded to a minimum radius of curvature depending on the gap shown in the table in the explanatory note to paragraph 5.1.1. This also applies, if the height of the projection, determined according to the procedure described in paragraph 1. of annex 6, is equal or less than 3.2 mm.

If the gap is located in a zone where a head impact test has to be carried out, the edges which can be contacted during the test(s) resulting from displacement of parts shall be protected by a minimum radius of 2.5 mm

Paragraph 5.1.1.

A sharp edge is an edge of a rigid material having a radius of curvature of less than 2.5 mm except in the case of projections of less than 3.2 mm, measured from the panel. In this case, the minimum radius of curvature shall not apply provided the height of the projection is not more than half its width and its edges are blunted.

Grills are considered to comply with the regulations if they meet the minimum requirements of the following table:

Gap between elements [mm]  Flat elements      Rounded elements min. radius [mm]
e/min. [mm]                min. radius [mm]
 0 – 10                                  1.5                0.25                               0.5
 10 – 15                                 2.0                0.33                               0.75
 15 - 20                                 3.0                0.50                               1.25

Paragraph 5.1.2.

During the test, it is determined whether parts within the impact zone used for reinforcement may be displaced or protrude so as to increase the hazards to passengers or the severity of injuries.

Paragraph 5.1.3.

These two concepts (level and lower edge of the instrument panel) may be distinct.
However, this point is included in paragraph 5.1. ( .... above the level of the instrument panel ...) and, therefore is applicable only where these two concepts are combined. In the case where the two concepts are not combined, i.e. where the bottom edge of the instrument panel is located below the level of the instrument panel, it will be considered under paragraph 5.3.2.1. by reference to paragraph 5.8.

Paragraph 5.1.4.

If a pull handle or knob has a width dimension equal to or more than 50 mm and is located in a
