Eight institutions from four countries participated in a round-robin study to determine the precision and bias of a liquidus temperature (T-L) procedure for waste glasses being adopted by ASTM International as ASTM C 1720-11. The participants of the round-robin study were asked to measure three different glasses with one or a combination of the following T-L measurement methods: a gradient temperature (GT) method, a uniform temperature (UT) method, and/or a crystal fraction extrapolation (CF) method. The T-L values reported by different institutions are generally consistent. The precision of T-L measurements with each method was evaluated and is presented herein. The round-robin glasses were all previously studied at Pacific Northwest National Laboratory and included ARG-1 (Glass A), Zr-9 (Glass B), and AmCm2-19 (Glass C), with measured T-L values spanning the temperature range of 960-1240 degrees C. A precision (i.e., standard deviation) for T-L has been obtained from the data, even though the data were not acquired for all three glasses using all three methods from each participating organization. Also, the article provides a brief overview and the importance of the T-L measurement.
