BS EN 40-7:2002 pdf download – Lighting columns — Part 7: Requirements for fibre reinforced polymer composite lighting columns
7 Design and design verification The design and verification of fibre reinforced polymer composite lighting columns shall be in accordance with EN 40-3-1 , EN 40-3-2 and prEN 40-3-3 and the additional requirements of annex B of this standard. The column shall be designed to sustain the dead loads and the wind loads, specified in accordance with EN 40-3-1 . The structural design of a lighting column shall be verified by either calculation in conformity to prEN 40-3-3, or by testing, in conformity to EN 40-3-2. If calculation is used, the method of calculation and parameters used shall be verified by appropriate physical type testing (see annex E).
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 IK08 as specified in EN 501 02 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.
After testing there shall be no indentation greater than 3 mm in depth when measured with a profile gauge. The test validates those products of which the outside diameter (or flat dimension) is equal to or less than the diameter being tested, with the same wall thickness and material strength. NOTE 1 A type is defined by the shape, the dimensions and thickness and material of the section at mid door height.
NOTE 2 For sections other than circular or octagonal the provisions defined above apply.
11 Internal finish and sharp edges
Cableways in columns shall conform to the requirements of prEN 40-2.
11.2 Access points
All access points used for the installation and fitting of electrical equipment shall be free from rough edges and burrs.
12 Corrosion protection
Fibre reinforced polymer composite lighting columns require no specific corrosion protection under this European Standard other than the sealing of cut edges which shall conform to 8.3.
NOTE Annex D provides recommendations that can help to extend the service life.
All columns and brackets shall be clearly and durably marked with:
a) the name or symbol of the manufacturer;
b) the year of manufacture;
c) a reference to this European Standard;
d) a unique product code.
NOTE The marking can be formed in the material, by painting or by securely fixed label.
14 Conformity control
14.1 Evaluation of conformity
14.1.1 Factory production control
Lighting columns and brackets shall be manufactured under a permanent factory production control system which incorporates the requirements of 1 4.3 to 1 4.8 and clauses 1 5 and 1 6.
The production control system shall include the following operations:
the specification and verification of raw materials and constituents;
the identification of the controlling and checking procedures for the design of new or modified products including the inspection and calibration of equipment;
