Abstract We present a detailed calculation of light element production in scale-covariant FRW cosmological models, where the modifications in the equations of nuclear kinetics due to scale-covariant kinetic theory effects are taken into account. The comparison of the results of our calculation with current observational data implies that the gauge function β(t) at primordial nucleosynthesis cannot deviate from its present value by more than a 1.5%. If we assume, as usual, that β is a power of time, these bounds leave little room for a possible strong equivalence principle violation.
