The freezing-point temperatures of two samples of 99.9999% pure indium in cells constructed such that the indium was in contact only with Teflon were measured with four standard platinum resistance thermometers and two resistance bridges, one bridge operating at 400 Hz and the other with square-wave dc. Although nominally of the same purity, one sample was purer than the other, with a difference in freezing-point temperature of 0.2 to 0.4 mK, the value depending on the bridge used for the measurements. The temperature, t68, of the purer sample as determined from dc measurements is (156.6342 +/- 0.0004) °C and as determined from ac measurements is (156.6345 +/- 0.0004) °C. The pressure dependence was determined to be (4.92 +/- 0.05) mK/(std. atm). Consequently, the triple-point temperatures are (4.92 +/- 0.05) mK lower than the freezing-point values. The indium freezing-point temperature would be a suitable defining fixed point for a temperature scale.
