The described procedure is to apply on single lines or subnetworks of public energy supply with rated voltages from 110 kV. It implies
- specification of a scheme which can determine a reduction of load capacity as a result of embrittlement of steel within pylons/lines depending on aging,
- requirements for the realisation of chemical analyses of constructional steels,
- requirements for the realisation of tensile tests for the determination of load carrying capacity of these structural components with increased content of nitrogen,
- evaluation of the results.
