Timber poles for overhead lines - Test methods - Determination of modulus of elasticity, bending strength, density and moisture content

Scope

This European Standard specifies methods of test to determine modulus of elasticity, bending strength, density and moisture content of solid wood poles for overhead transmission and telecommunication lines. It is applicable to both hardwood and softwood poles.
This standard covers only single poles under cantilever and/or compression loading. For example, this standard does not cover poles used as beams.
The provision of poles for use in any overhead line or cable infrastructure shall take into account a range of factors not covered by this standard which will necessitate the specification by the end user of complementary and synonymous attributes to those defined in this standard. This refers to requirements for a number of factors including safety, overhead plant, handling, fittings, installation machinery and working practices including climbing.
