The limits on time-reversal invariant tensor-type weak currents from nuclear and neutron beta decays are evaluated including most recent experimental data. We find that -0.14 x 10(-2) < (C-T + C-T')/C-A < 1.4 x 10(-2) and -0.16 < (C-T-C-T')/C-A < 0.16 (90% C. L.), while for the case C-T = C-T' the limits are 0.0 x 10(-2) < C-T /C-A < 0.4 x 10(-2). These limits are shown to be more stringent than those from recent measurements of the radiative pion decay. In addition, the sensitivity of future 10(-3)-level correlation measurements is investigated.
