April 2011 - Change to spray-suppression laws legislation!

 

On 29 October 2010, Directive 91/226/EEC came into force for the spray-suppression systems on certain categories of motor vehicles and trailers. Since that date the requirements of this Directive have applied to new types of vehicles.  

On 9 April 2011 Directive 2010/19/EC came into effect supplementary to Directive 91/226/EEC. This contains other requirements relating to the mounting of the spray-suppression system: certain dimensions and angles are different.

What does the change in the legislation mean?

What categories of vehicles do the changes apply to?

N2:        Motor vehicles for transporting goods with a maximum mass exceeding 7½  tonnes
N3:        Motor vehicles for transporting goods with a maximum mass exceeding 12 tonnes Motor vehicles for transporting goods with a maximum mass exceeding 12 tonnes
O3:        Trailers and semi-trailers with a maximum mass between 3½ and 10 tonnes
O4:        Trailers and semi-trailers with a maximum mass exceeding 10 tonnes

When does the change become effective?

The change comes into force with effect from 9 April 2011 and relates to the following implementation dates for 91/226/EEC.

 

Category Implementation date
  New vehicles Existing vehicles
Incomplete and complete vehicles 29 October 2010 29 October 2012
Special purpose vehicles 29 October 2010 29 October 2012
Complete vehicles N2, N3 29 October 2012 29 October 2014
Complete vehicles O3, O4 29 October 2011 29 October 2013

 

What changes under the new legislation?

  • The type-approval mark should be clearly and legibly marked, even after fitting, on the spray-suppression device.
  • The distance (c) between the outside of the tyre and the inner edge of the valance must not be more than 100 mm.  
  • The mudguard must have a minimum width (q) of the tyre (b), or, with twin wheels, cover the entire width (t) of two tyres.  
  • The width of the mud flap must be equal to dimension (q) except when the mud flap is within the mudguard. Then the mud flap must be at least as wide as the contact patch of the tyre or tyres. A tolerance of 10 mm applies to the part that is on the inside of the mudguard.
  • The distance between the highest and lowest point of the spray-suppression system must be a minimum of 45 mm behind a vertical line passing through the centre of the wheel at all points. Before this line, this distance may reduce gradually.
  • For single or multiple axles the forward edge must extend forwards to reach the line O-Z which may be at an angle of no more than 45° above the horizontal. The rearmost edge must not end more than 100 mm above a horizontal line through the centre of the wheel .
  • In the case of multiple axles the regulation for the angle of line O-Z only applies to the foremost axle and the regulation for the rear only applies to the rearmost axle.
  • In the case of single axles the distance from the centre of the axle to the lower edge of the mudguard must not be more than the following distances and radii: 
  • Air suspension
    • Steered or self-steered wheels, from the front edge to the rear edge (C-A): Rv = 1.5 R
    • Non-steered wheels, from the front edge to the rear edge (C-A): Rv = 1.25 R
  • Mechanical suspension
    • General rule: Rv ≤ 1,8 R
    • Vehicles > 7½ tonnes: Rv ≤ 1,5 R

The above does not apply to multiple axles. Here the valance can extend horizontally from the centre of the foremost wheel to the centre of the rearmost wheel.

The maximum height of the lower edge of the rain flap to the road surface must not be more than200 mm. For the rearmost   axle this can be a maximum of 300 mm if this is considered permissible taking account of the technical characteristics of the suspension (roll on/off ferries) .
