  • Description: <jats:p>Eight institutions from four countries participated in a round‐robin study to determine the precision and bias of a liquidus temperature (<jats:italic>T</jats:italic><jats:sub>L</jats:sub>) procedure for waste glasses being adopted by <jats:styled-content style="fixed-case">ASTM</jats:styled-content> International as <jats:styled-content style="fixed-case">ASTM C</jats:styled-content> 1720‐11. The participants of the round‐robin study were asked to measure three different glasses with one or a combination of the following <jats:italic>T</jats:italic><jats:sub>L</jats:sub> measurement methods: a gradient temperature (<jats:styled-content style="fixed-case">GT</jats:styled-content>) method, a uniform temperature (<jats:styled-content style="fixed-case">UT</jats:styled-content>) method, and/or a crystal fraction extrapolation (<jats:styled-content style="fixed-case">CF</jats:styled-content>) method. The <jats:italic>T</jats:italic><jats:sub>L</jats:sub> values reported by different institutions are generally consistent. The precision of <jats:italic>T</jats:italic><jats:sub>L</jats:sub> 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 <jats:styled-content style="fixed-case">ARG</jats:styled-content>‐1 (Glass A), Zr‐9 (Glass B), and AmCm2‐19 (Glass C), with measured <jats:italic>T</jats:italic><jats:sub>L</jats:sub> values spanning the temperature range of 960–1240°C. A precision (i.e., standard deviation) for <jats:italic>T</jats:italic><jats:sub>L</jats:sub> 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 <jats:italic>T</jats:italic><jats:sub>L</jats:sub> measurement.</jats:p>
