Timber poles - Basic requirements and test methods
ISO 15206:2010 specifies the requirements for grading, test methods, determination of characteristic values, methods of specifying durability and sizes of single poles manufactured from solid timber for telecommunications and electrical distribution purposes, either preservative treated or untreated, under cantilever or compression loading.
It 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, as well as 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 durability and preservative treatment of wood poles.
It is applicable to both softwood and hardwood poles.
