BS EN 40-4-2005 pdf download.Lighting columns Part 4: Requirements for reinforced and prestressed concrete lighting columns.
7.5.2.2 Prestressed concrete columns (for spun concrete see 7.5.2.3)
Where verified by tests defined in EN 40-3-2, transverse reinforcement shall not be necessary.
7.5.2.3 Reinforced or prestressed spun concrete columns
The minimum transverse reinforcement ratio shall be:
a) for column diameters at the foot equal to or greater than 800 mm, 0,15 % of the longitudinal concrete section;
b) for column diameters at the foot less than 400 mm, 0.05 % of the longitudinal concrete section;
c) for column diameters at the foot equal to or less than 800 mm and greater than 400 mm by linear interpolation between the above mentioned values.
8 Protection against mechanical impact
A type test shall be carried out on each type of column base, or part, provided that each end of the part extends at least 0,3 m above and below the door opening. The test shall conform to an impact protection category of 1K08 as specified in EN 62262 with the door fitted.
The test equipment shall be either impact pendulum hammer or vertical free fall hammer. The manufacturer shall declare the test method used.
NOTE A single test method will be adopted when the EN 40 series of product standards is revised.
The number of impacts shall be five and shall be apphed around the circumference at the mid height of the door. For circular columns these shall be equally spaced around the remaining circumference exduding the door. For octagonal columns these shall be on each of the adjacent faces excluding the door.
Alter testing, no visible crack shall appear.
The test shaN validate those products with an outside diameter (or flat dimension) equal to or less than the diameter being tested, with the same wall thickness and matenal strength.
For mechanical impact test, a type shall be defined by the shape, the dimensions and type of concreteireinforcernent of the section at mid door height.
For sections other than circular or octagonal, the provisions defined above shall apply.
9.2.1 Cableways
Cableways shall conform to the requirements of EN 40-2:2004. 4,4.4.
9.2.2 Access points
AU access points used for the installation and fitting of electrical equipment shall be free from rough edges and burrs.
10 Marking and labelling
AU columns arid brackets shall be cleaily and durably marked with:
a) name or symbol of the manufacturer:
b) year of manufacture;
C) reference to this document;
d) unique product code.
The marking shall be formed either in the matenal or by painting, hard stamping or by a securely fixed label.
Where applicable, such marking shall not obscure or lead to confusion with regulatory marking. NOTE For CE marking refer to Annex ZA.
11 Technical documentation
11.1 General
The detailing of the column, induding geometrical data with the complementary properties of materials and inserts, shall be given in technical documentation, which includes the construction data, such as the dimensions, tolerances, layout of reinforcement, the concrete cover, required support conditions and lifting conditions.
For columns designed in accordance with 6 a), mounting and fixing details shall be provided. The composition of technical documentation is given in EN 13369:2004, Annex 0.
11.2 Handling, storage and transportation
The manufacturer shall gave information for handhng and storage to prevent damage or deterioration. The manufacturer shall also give information for supporting and attaching the column segment to the vehide used for transport.
11.3 Traceability
Delivered product or products batches shall be definitely identifiable and traceable with regard to their production data. For this purpose, the manufacturer shall establish and maintain for seven years the records required in the relevant technical specification, and shall mark the products or their delivery documents accordingly.
12 Conformity control
12.1 General
Conformity of the product with the requirements shall be demonstrated by:
— initial type testing;
— factory production control.
12.2 Evaluation of conformity
12.2.1 Factory production control
Factory production control shall be in accordance with EN 13369:2004. 6.3.
Inspection procedures for columns shall be conducted in accordance with Annex B and EN 13369:2004, Annexes Dl, D3 and D.5.
The test on the potential compressive strength in EN 13369:2004, Annex D3.1, item 8 shall be replaced by flexural strength test (in accordance with EN 12390-5) on moulded specimens, if the required flexural strength has been determined during type testing.
12.2.2 Initial type testing
12.2.2.1 General
Type testing shall be in accordance with EN 13369:2004, 6.2 and Annex C of this document.BS EN 40-4-2005 pdf download.
