UN R46 — Supplement 10 to the 04 series of amendments

Under new paragraph 6.1.1.9., paragraph 6.1.1.3. does not apply to mirrors with the lower edge mounted not less than 2 m above the ground. Under new paragraph 6.2.2.1.6., paragraph 6.2.2.1.1. does not apply to CMS with the lower edge mounted not less than 2 m above the ground. In both cases, the height applies when the vehicle is under a load corresponding to its maximum technical permissible mass.

New paragraph 6.2.2.1.2. exempts parts of the external surface protruding less than 5 mm from paragraph 6.2.2.1.1., but their outward facing angles must be blunted. The new paragraph continues “and are considered save where such parts protrude less than 1.5 mm”. On a convex surface, the projection may be found directly or from a drawing of an appropriate section of the installed component (para. 6.2.2.1.2.1.). On other surfaces, if simple measurement is not possible, a 100 mm diameter sphere is moved over the component in constant contact (para. 6.2.2.1.2.2.). The projection is the maximum variation of the distance of the sphere centre from the nominal line of the panel (see new Figure 1). The paragraph on fixing holes and recesses is now paragraph 6.2.2.1.3.

Under paragraph 6.2.2.1.4., camera and monitor parts outside the vehicle with a Shore A hardness of less than 60 are exempt from the relevant provisions. A rigid support is no longer a condition for these parts. New paragraph 6.2.2.1.5. covers camera and monitor parts inside the vehicle with a Shore A hardness of less than 50 on a rigid support. For these parts, paragraph 6.2.2.1.1. applies only to the support. Before this supplement, one paragraph covered camera and monitor parts with a Shore A hardness of less than 60 on a rigid support. For those parts, paragraph 6.2.2.1.1. applied only to the support, and the text did not separate parts inside and outside the vehicle.
