BS EN 40-3-3:2013

What is BS EN 40-3-3 - Lighting columns design and verification about?  

Lighting columns provide lights in outdoor areas such as streets and parks. The BS EN 40 series is a European Standard series that discusses lighting columns.

BS EN 40-3-3 specifies the requirements for the verification of the design of lighting columns by calculation.

BS EN 40-3-3 applies to light columns of nominal height (including any bracket) not exceeding 20 m.

In following this approach, simplifications appropriate to lighting columns have been adopted. These are:

• The calculations are applicable to circular and regular octagonal cross-sections
• The number of separate partial safety factors have been reduced to a minimum
• Serviceability partial safety factors have a value equal to unity

Note 1: Special structural designs to permit the attachment of signs, overhead wires, etc. are not covered by BS EN 40-3-3.

Note 2: The requirements for lighting columns made from materials other than concrete, steel, aluminium, or fibre-reinforced polymer composite (for example wood, plastic, and cast iron) are not specifically covered in BS EN 40-3-2.

Note 3: Passive safety and the behaviour of a lighting column under the impact of a vehicle are not addressed. Such lighting columns will have additional requirements (see EN 12767).

Who is BS EN 40-3-3 - Lighting columns design and verification for? 

BS EN 40-3-3 on ‘lighting columns design and verification by calculation’ is useful for: 

• Relevant government / municipal authorities
• Roadway / highway authorities
• Lighting equipment manufacturers and suppliers
• Product design engineers
• Quality control personnel
• Engineers

Why should you use BS EN 40-3-3 - Lighting columns design and verification?  

Column lighting provides general ambient light in wide settings, providing a sense of safety at night. Fibre-reinforced polymer composite lighting columns are covered in this standard in conjunction with EN 40-7.

BS EN 40-3-3 includes performance requirements for horizontal loads due to wind. BS EN 40-3-3 provides guidance on acceptance of design for strength, deflection requirements, structural strength requirements, characteristic strength of materials, calculation of moments, the strength of cross-section, reinforced openings in regular cross-sections, and permissible modifications to the verified column.

BS EN 40-3-3 provides you with lighting design criteria, lighting design considerations, and the schedule of specific lighting requirements that need to be verified, and that verification procedure has also been provided.

BS EN 40-3-3 aids you in achieving passive safety, environmental, and long-term cost-cutting benefits. Aside from that, it lowers maintenance costs by reducing road closures and possession orders, reducing operator time, and reducing the time that maintenance staff must spend conducting structural examinations in dangerous roadside and trackside situations.
