| AS/NZS 1768 | The Australian standard AS/NZS 1768:2007, titled "Lightning Protection," is a technical standard that provides guidelines and requirements for the design, installation, and maintenance of lightning protection systems in Australia and New Zealand. This standard aims to protect structures and their occupants from the potential hazards associated with lightning strikes. AS/NZS 1768:2007 covers various aspects of lightning protection, including: Risk assessment: The standard provides a methodology for assessing the risk of lightning strikes to a specific structure based on factors such as location, height, and materials used in construction. Design principles: It outlines the fundamental principles and requirements for designing an effective lightning protection system, including the use of air terminals (lightning rods), down conductors, and earthing systems. System components: The standard specifies the materials, dimensions, and installation requirements for various components of a lightning protection system, such as air terminals, down conductors, and earth electrodes. Installation guidelines: It provides detailed instructions for installing lightning protection systems, including the proper placement of air terminals, routing of down conductors, and connection to earthing systems. Maintenance and testing: AS/NZS 1768:2007 outlines the necessary maintenance and testing procedures to ensure the ongoing effectiveness of a lightning protection system, such as regular inspections, testing of earth resistance, and replacement of damaged components. Compliance with AS/NZS 1768:2007 is typically required for new construction projects and renovations involving structures that are at risk of lightning strikes. Adhering to this standard helps ensure the safety of buildings and their occupants by providing an effective means of diverting lightning currents away from the structure and into the earth.
