The yield point (Ts) is the temperature at which, when thermal expansion is measured, the apparent swelling ceases and contraction begins. It occurs at a temperature approximately 40 to 60°C higher than the slow-cooling point.
It is defined in the Japanese standard JOGIS 08-2003 and is denoted by "Ts." Based on expansion measurements, it provides a clue as to the temperature range at which the glass begins to soften.
