The Benchmarks signify a consensus of authorities with regards to essential requirements for construction and overall performance of qualified layouts and solutions.
Creating a method of air terminals projecting only 10 inches over these structural points of emphasis and along ridges and edges has been confirmed, in much more than a century of follow, to supply interception of some ninety five% of recorded lightning flashes, including the most violent.
