Draft Scope/Description:

1 Scope


This Standard covers the protection from lightning of:

recreational, residential, insititutional, medical, agricultural, industrial, commercial, military, and telecommunications buildings and structures;

tall, slender structures such as smoke stacks, silos, tanks, towers, masts and poles; and

immobile property such as equipment, tents, fences, trees, and solar arrays;

high-risk structures with dangerous contents such as explosives and flammable goods.


This Standard covers the protection from lightning of structures housing electrical generation, transmission, and distribution systems, as well as structures housing communication systems, but not the equipment or installation requirements for such systems.


This Standard does not cover installation requirements for early streamer emission systems or charge dissipation/charge transfer systems.


This Standard also contains non-mandatory sections devoted to the nature of lightning and the general principles upon which lightning protection is based, so that the user of the Standard will be able to assess the need for lightning protection in the case of any given structure (see Appendices).


The values given in SI (metric) units are the standard. The values given in parentheses are for information only.


Clause 2 contains a list of standards referenced in this Standard, and sources from which these reference standards may be obtained.
