3 Terms and definitions, symbols and abbreviations
For the purposes of this European Standard, the symbols and abbreviations given in ISO 4 apply. The photometric terms and definitions given in CIE 17.4 and the sign descriptions given in CIE 74 also apply, together with the following :
3.1
fixed sign
sign which is intended to remain fixed in position and whose supports are usually set into the ground
3.2
protective edge
fabrication intended to reinforce the edge of the sign and to reduce the severity of personal injury in the event of bodily impact with the sign edge
3.3
substrate
material used to support the non-retroreflective and retroreflective sign face materials
3.4
standard shape sign faces
circles, triangles, squares, diamonds and octagons containing legends in accordance with the provisions of the Vienna Convention
4 Dimensions and tolerances
4.1 Dimensions and tolerances of standard shape sign faces
The dimensions and tolerances of standard shape sign faces shall conform to the customer’s requirements.
4.2 Corner radii
Unless otherwise specified in the customer’s requirements the corner radii shall be not less than 10 mm.
5 Performance requirements
5.1 Design
5.1.1 General
Steel constructions and steel mounting elements shall conform to ENV 1993-1-1:1992.
Aluminium constructions shall conform to ENV 1999-1-1.
Timber constructions shall conform to ENV 1995-1-1.
Other materials are acceptable but if they are used the fixed signs shall conform to this standard.
The colour of the back of the substrate shall be in accordance with the customer’s requirements.
Welded fabrications shall comply with the appropriate codes and standards.
5.1.2 Piercing
When sign substrates are stiffened with additional reinforcing members, these shall be fixed to the sign substrate to conform with Table 1.
5.1.4 Fixings Sign fixings shall fit sign supports such that they prevent rotation around the support and enable conformance to 5.3.1 to 5.3.3. Sign fixings shall also conform to 5.3.5.
5.1.5 Supports Supports shall conform to 5.3.1 to 5.3.5 and 5.3.8. Hollow supports shall be enclosed at the top to prevent moisture ingress.
5.1.6 External lighting luminaires External lighting luminaires shall conform to EN 60598-1 and to 5.3.8. The structural design shall include the whole structure consisting of housing, support and fixings. Lamps shall be protected by a housing against rain, wind load and other adverse outdoor conditions. Luminaire housings and luminaire panels shall conform to 5.3.8. NOTE Luminaires should be mounted so as not to obscure the driver’s view of the sign face.
5.1.7 Sign housings for transilluminated signs Sign housings for transilluminated signs shall conform to 5.3.8 and shall be designed to ensure reliable transfer of all static and dynamic forces to the fixing and mounting structures. The walls of the housing shall be designed to satisfy the static requirements. Corners shall be rounded. The design shall ensure that rainwater does not run off the housing and down the sign face.
5.1.8 Base compartments Where electrical apparatus is to be housed in a sign post, the post shall be fitted with a base compartment conforming to EN 40-5. Each base compartment shall be fitted with a secure lock and shall conform to 5.3.8.
