DIN | 2011-02 | 42 |
This standard covers single poles for telecommunications and electrical distribution purposes, either preservative treated or untreated, under cantilever or compression loading (it does not cover poles used as beams). It covers test methods, determination of characteristic values, and methods of specifying durability and sizes. It also establishes principles for visual or machine grading.This standard does not quantify the service life that may be expected from a pole.NOTE This will depend on its geographical location, the associated climate of its service environment and either the natural durability of the heartwood of the species selected, or the combination between selection of species, preservative type, and requirements of retention and any incised zones.This standard applies to both softwood and hardwood poles.This standard specifies:- the methods of measuring the sizes of solid wood poles for overhead transmission and telecommunication lines and permissible deviations that are taken into account for the acceptance of the poles,- the requirements for handling and the characteristics for visual strength grading of softwood and hardwood poles. It also specifies the marking requirements,- the methods of test to determine characteristic values for modulus of elasticity and bending strength of any population of wood poles, and moisture content of solid wood poles,- the requirements for natural durability and preservative treatment of wood poles.
