Isolated lightning protection concept (S19292)

Designing of External Lightning Protection Systems (without Earth-Termination Systems) with 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:

  1. Fully completed project data sheet (form provided by DEHN (C&P))
  2. 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)
  3. Optional: Conducting a fee-based on-site as-built survey / project meeting (S03070)


Specification:

  1. 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
  2. Dimensioning of the down conductors of the lightning protection system (LPS) according to the selected protection class of the LPS
  3. Graphic representation of the air-termination systems and down conductors on the building / plant to be protected
  4. 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)
  5. Creation of a bill of materials of the lightning protection components used
  6. Separation distance calculation according to section 6.3 of DIN EN 62305-3 or IEC 62305-3
  7. Optional: Creating a fee-based design of the earth-termination system for external lightning protection systems (S19295)
  8. Optional: Creating a fee-based design of surge protection measures
    (S05596)


Scope:

  1. 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
  2. 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)
  3. Drawings of installation details of the lightning protection components used
  4. Material bill of materials (also preparation of a material quotation with existing customer conditions for lightning protection material)
  5. Provision of product data sheets, manufacturer's declarations and installation instructions (if available) of the components used in the design
  6. 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
