Designing of External Lightning Protection Systems (without Earth- Termination Systems) with Isolated and Non-Isolated Air-Termination Systems and Down Conductors
Specification Basis:
DIN EN 62305-3 (VDE 0185-305-3) in the version valid at the time the order is placed;
(If, at the time the order is placed, the above standard is in a transition period between two versions, the newer version shall apply.)
Alternative: IEC 62305-3 in the version valid at the time the order is placed;
(In the case of IEC standards, there is no transition period between two versions.)
Requirements:
- Fully completed project data sheet (form provided by DEHN (C&P))
- Provision of drawings of the building / plant to be protected in electronic form in one of the following data formats:
• 2D: .dxf, .dwg, pdf (not scanned!)
• 3D: .dwg, ifc, dgn, skp, stl, stp
• Optional: fee-based commissioning of a creation of drawings (S04555) or fee-based commissioning of a 3D scan for the generation of 3D data of the building / plant to be protected (S10366) - Optional: Conducting a fee-based on-site as-built survey / project meeting (S03070)
Specification:
- Dimensioning of the air-termination systems of the lightning protection system (LPS) according to the selected protection class of the LPS with the rolling sphere method according to section 5.3.3 of DIN EN 62305-3 or IEC 62305-3, and taking into account the wind loads according to EUROCODE 1
- Dimensioning of the down conductors of the lightning protectionsystem (LPS) according to the selected protection class of the LPS
- Graphic representation of the air-termination systems and down conductors on the building / plant to be protected
- Protected volume construction of the air-termination systems (2D or 3D depending on the format of the data provided and the complexity of the building / plant to be protected)
- Creation of a bill of materials of the lightning protection components used
- Separation distance calculation according to section 6.3 of DIN EN 62305-3 or IEC 62305-3
- Optional: Creating a fee-based design of the earth-termination system for external lightning protection systems (S19295)
- Optional: Creating a fee-based design of surge protection measures (S05596)
Scope:
- Textual description of the lightning protection concept / lightning protection solution with an explanation of the solution principles and a list of possible boundary conditions to be observed in the practical implementation of the design
- Drawings of the roof view and the protected volume construction (2D or 3D depending on the format of the data provided relating to the building / structure to be protected)
- Drawings of installation details of the lightning protection components used
- Material bill of materials (also preparation of a material quotation with existing customer conditions for lightning protection material)
- Provision of product data sheets, manufacturer's declarations and installation instructions (if available) of the components used in the design
- Optional: Free provision of tender specification texts of the components used in the design
Document Format:
- Handover of all documents electronically in PDF format
- Handover in open formats (e.g. .docx, .xlsx, .dwg, .nwd) with separate, signed handover document possible
