IEC 60105:1958 pdf download,Recommendation for commercial-purity aluminium busbar material.

IEC 60105:1958 “Recommendation for commercial-purity aluminium busbar material” specifies reference electrical properties for commercial-purity aluminium used as busbar material. Its purpose is to provide a standardized basis (mainly related to electrical resistance/conductivity behavior) so manufacturers and engineers can describe and evaluate aluminium busbars consistently, regardless of the cross-sectional shape of the bar.

In practice, this means the standard is aimed at the material used in power transmission and distribution hardware (busbars), ensuring that electrical calculations and comparisons that depend on aluminium’s conductivity/resistance can be performed using agreed reference values for commercially pure aluminium. Since conductivity/resistance can vary with material state and processing, IEC 60105 frames “commercial-purity aluminium” in terms that support consistent engineering use across different parties and applications.
