Bibliography

This Standard specifies requirements for precast concrete poles (also commonly called masts) (either all of a piece or composed of elements), reinforced and/or prestressed as structural elements; they may be hollow or solid and may receive or include additional components (e.g. cross-arms, platforms etc.), inserts and connectors. Additional elements may be connected to pole elements.Structures made from such elements in mono- or multi-legged form may be used for :- overhead electrical lines ;- telecommunication lines ;- overhead electrical lines for railways, trams and similar ;- supports for lighting ;- supports for loudspeaker installation ;- antenna and telecommunication poles ;- supports for wind turbines ;- and similar installations.This Standard does not cover lighting columns for use in traffic circulation areas.
