BS EN 40-7-2002 pdf download.Lighting columns Part 7 : Requirements for fibre reinforced polymer composite lighting columns.
This part of this BS EN 40 specifies the performance requirements for fibre reinforced polymer composite lighting columns for which the main intended use is road lighting. It includes materials and test methods. The composite materials considered are those constructed of a resin matrix reinforced by a high strength fibrous material. 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 European Standard specifies the classes of performance related to the essential requirements of resistance to horizontal (wind) loads, and performance under vehicle impact (passive safety) in application of Essential Requirement No 4 Safety in Use measured according to the corresponding test methods included in this European Standard or available in separate European Standards.
It provides for the evaluation of conformity of the product to this European Standard.

8 ConstructIon and Properties
8.1 Pigmentation
Composite laminates shall be completely pigmented with a uniform colour throughout the structure.
8.2 Surface finish
The columns and brackets shall have a smooth finish with a suitable surface coating to prevent fibres breaking out of the surface during the design life of the column.
NOTE This surface coating can be in the form of a surface veil producing a protective resin rich layer integral with the structure, or an appropriate polyurethane or acrylic coating system or a gel coat backed by a suitable layer of chopped strand mat.
8.3 Cut edges
All cut edges to the extremities or to openings in the column shall be sealed to prevent the ingress of water or any other contaminants. Sealing shall be through the application of the parent resin or a suitable alternative and shall be completed prior to the application of any external coatings.
8.4 Mechanical properties
The characteristic propertIes of the resulting laminates shall be determined in accordance with annex C.
9 Joints
All joints shall be designed and verified in accordance with clause 7.
10 Protection against mechanical Impact
A type test shall be carried out on each type and nominal height of column, or part column provided each end of the part extends at least 0.3 m above and below the door opening, and shall comply with an impact protection category of lKO8 as specified in EN 50102 with the door fitted.
The test equipment shall be either impact pendulum hammer or vertical free fall hammer.
The number of impacts shall be five and shall be applied around the horizontal circumference at the mid height of the door. For circular columns the impact points shall be equi-spaced around the remaining circumference excluding the door. For octagonal columns these shall be on each of the adjacent faces excluding the door.BS EN 40-7-2002 pdf download.
