Abstract
The virtual massive gauge boson effects on several observables in the process of charged fermion pairs production at e+e- colliders are computed up to the TeV energy range in the Standard Model, working in the ``Z-peak subtracted'' representation. It is shown that these effects increase regularly with energy, approaching the typical ten percent relative size. A careful numerical evaluation is proposed, where the conditions dictated by gauge invariance are consistently implemented.
