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...
