PrzeslawskiInstitute of Experimental Physics, University of Wroclaw, Max Born Sr.,9, Poland ͑Received 15 July 1997͒Improved experimental resolution and computer aided data analysis of hysteresis loops at TϷT C in uniaxial ferroelectrics triglycene sulfate ͑ordinary critical point͒, and triglycine selenate ͑quasitricritical point͒ show that scaling holds in a wide range of scaled fields spanning many orders of magnitude, well beyond the asymptotic region (͉TϪT C ͉→0), and that the behavior of metastable experimental points (EϽ0,PϾ0) approaches the theoretical branch of the respective scaling equation as T→T C . ͓S0163-1829͑98͒05102-9͔
