BS EN 40-2-2004 pdf download.Lighting columns Part 2 : General requirements and dimensions.
This BS EN 40-2 specifies the requirements and dimensions for lighting columns, brackets, base compartments, cableways and earthing terminals. It applies to post top columns not exceeding 20 m height for post top lanterns and columns with brackets not exceeding 18 m height for side entry lanterns.
This Part does not attempt to restrict the actual appearance or shape of the column or bracket. The majority of lighting columns are normally of a stepped tubular, round, octagonal or polygonal cross- section. Lighting columns may be manufactured from materials other than those listed in the foreword (e.g. wood, plastic, cast iron) or in other forms (e.g. lattice and telescopic).
This document specifies performance related to the essential requirements of resistance to horizontal
(wind) loads and performance under vehicle impact (passive safety) in support of the Essential
Requirement No 4 Safety in use measured according to the corresponding test methods included in
this document or available in separate documents.

4.2 Columns with brackets
4.2.1 The nominal height (h in m) shall be the height from ground level at the column to the height of the point of entry to the lantern as shown in Figure 2.
Values of h should be selected from Table 2.
4.2.2 The bracket projection (w in m) shall be the horizontal dimension from the column axis to U,e point of entry to the lantern as shown in Figure 2.
Values for w should be selected from Table 3.
NOTE It is recommended that w should be equal to or less than h14,
4.2.3 The lantern fixing angle (a in degrees) shall be as shown In Figure 2. Values of a should be selected from Table 4.
4.4 Base compartments and cableways
4.4.1 Compartment dimensions
When a base compartment is supplied its free space, height, width and depth dimensions shall be stated.
4.4.2 Compartment door
The door shall either be made from the materials specified in the relevant part of EN 40, or from other materials for which the requirements shall be specified.
On metal columns the doors shall have an equivalent degree of corrosion protection to that provided for the column. On concrete columns the doors shall have an equivalent degree of corrosion protection to that provided for doors on metal columns.
The door shall be secured by a locking mechanism to resist unauthorized entry.
NOTE For the protection category of the door see 44.5.
4.4.3 Attachment of electrical equipment
The compartment shall be provided with means of attaching electrical equipment. Where a metal tray is used, it should be given the same degree of corrosion protection as that provided for metal compartment doors. Where a baseboard is used, it should be manufactured from material, which is non-hygroscopic.
4.4.4 ElectrIcal cableways
Cableways from the base compartment to the lantern connection shall have a containing diameter of not less than 18mm.
Cableways from the cable entry slot to the base compartment shall have a containing diameter of not less than 50 mm.
Au cableways should be smooth and free from obstruction with no sharp edges. flashes or burrs which might cause abrasion to the cables.
4.4.5 Protection category
Parts of the column above ground level including the door when fitted shall conform to the following protection categories in EN 60529.BS EN 40-2-2004 pdf download.
