Regard should then be taken of the extra requirements necessary for the components to be installed in such conditions.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.EN 62305-1, Protection against lightning Part 1: General principles (IEC 62305-1)EN 62305-3, Protection against lightning Part 3: Physical damage to structures and life hazard(IEC 62305-3, mod.)EN 62305-4, Protection against lightning Part 4: Electrical and electronic systems within structures(IEC 62305-4)3 DefinitionsFor the purposes of this document, the following terms and definitions apply.3.1earth electrode inspection housingmetallic or non-metallic enclosure that houses the down conductor/earth termination connection for inspection and testing purposes. This consists of a housing and a removable lid3.2earth electrode sealwater pressure seal used in conjunction with an earth rod electrode that passes through the foundation of the building, so preventing ground water from entering the building4 RequirementsAll earth electrode inspection housings and earth electrode seals shall be so designed and constructed that in normal use their performance is reliable and without danger to persons and the surrounding.The choice of a material depends on its ability to match the particular application requirements.4.1 DocumentationThe manufacturer or supplier of the earth electrode inspection housing and earth electrode seals shall provide adequate information in his literature to ensure that the installer can select and install the materials in a suitable and safe manner, in accordance with EN 62305-3.Compliance is checked by inspection.4.2 Earth electrode inspection housingThe design of the earth electrode inspection housing shall be such that it carries out its function of enclosing the down conductor/earth rod termination in an acceptable and safe manner, and has sufficient internal dimensions to permit the assembly/disassembly of the earth rod clamp. The housing body shall be deep enough to permit the lid to sit flush on the body without fouling on the rod/conductor/clamp assembly.The material of the earth electrode inspection housing shall be compatible with the associated down conductor and earth rod termination and comply with the tests given in 6.2.The maximum total weight of the inspection housing shall be 25 kg.4.3 Earth electrode sealThe design of the earth electrode seal shall be such that it carries out its function of preventing ground water bi-passing the earth rod and entering the basement of a building, in an acceptable and safe manner.The material of the earth electrode seal shall be compatible with its surrounding environment and comply with the tests given in 6.3.5 MarkingAll products complying with this standard shall be marked at least with the following:a)manufacturer's or responsible vendor's name or trade mark;b)identifying symbol.Where this proves to be impractical the marking in accordance with b) may be given on the smallest packing unit.NOTE Marking may be applied for example by moulding, pressing, engraving, printing adhesive labels, or water slide transfers.Compliance is checked in accordance with 6.4.6 Tests6.1 GeneralThe tests in accordance with this standard are type tests.6.1.1 In normal use according to the manufacturer's or supplier's instructions.6.1.2 All tests are carried out on new specimens.6.1.3 Unless otherwise specified, three specimens are subjected to the tests and the requirements are satisfied if all the tests are met. If only one of the specimens does not satisfy a test due to an assembly or a manufacturing fault, that test and any preceding one which may have influenced the results of the test shall be repeated and also the tests which follow shall be carried out in the required sequence on another full set of specimens, all of which shall comply with the requirements.NOTE The applicant, when submitting a set of specimens, may also submit an additional set of specimens which may be necessary should one specimen fail. The testing station will then, without further request, test the additional set of specimens and will reject only if a further failure occurs. If the additional set of specimens is not submitted at the same time, the failure of one specimen will entail rejection.6.2 Earth electrode inspection housingAll tests shall be performed on three new lid samples using one housing.6.2.1Load testThe specimens shall be tested after a curing period. In the case of concrete this shall be a minimum of28 days and 7 days for all other materials.The test is carried out on a complete assembly and prepared according to the manufacturers instructions.The housing of the specimen shall be cast in a concrete base following the manufacturer instructions. The arrangement should be placed on a rigid support.An example for an arrangement is shown in Figure 1.142 345556Legend1 Force4Housing2 Circular steel plate5Concrete base3 Removable lid6Rigid supportFigure 1 Test arrangementThe product applicable for heavy duty usage i.e. vehicular traffic areas shall be subjected to a force of40 kN vertically applied through a circular steel plate with a 170 mm ± 0,5 mm diameter and athickness of 20 mm ± 1 mm with an edge radius of approximately 2 mm.The product applicable for light duty usage i.e. walkways etc shall be subjected to a force of 15 kNvertically applied through a circular steel plate with a 130 mm ± 0,5 mm diameter and a thickness of20 mm ± 1 mm with an edge radius of approximately 2 mm.The centre of the circular plate should be positioned over the centre of the lid.The force shall be gradually applied over 60 s ± 10 s and maintained for 120 s ± 5 s.BS EN 50164-5:2009EN 50164-5:2009 7 6.2.2Acceptance criteriaDuring the test the lid shall show no deflection greater than 7 mm. After the test, the samples shall show no signs of disintegration, nor shall there be any cracks visible to normal or corrected vision without additional magnification. One minute after the load has been removed, there shall be no permanent deformation exceeding 3 mm.The specimens are deemed to have passed the tests if all samples meet the above requirements.6.3 Earth electrode seal6.3.1Sealing testThe earth electrode seal shall be assembled in accordance with the manufacturer's instructions in a typical test bed that proves its intended application (as shown in Figure 2).5 bar214534Legend1 Tank2 Earth electrode3 Earth electrode seal arrangement4 Seals5 AirFigure 2 Test arrangementA minimum air pressure of 5 bar shall be applied for 24 h continuous to one end of the seal arrangement.6.3.2Acceptance c
