The standard ISO 7884-6:1987 Glass viscosity and viscosity fixed points - Part 6: Determination of softening points specifies the method for determining the softening point of Glass. The softening point is the temperature at which the material begins to change from a solid to a softening state during the heating process of Glass, and is commonly used to evaluate the processing performance of Glass at high temperatures. The standard describes the process of heating a glass sample using standardized equipment and determining its softening point. Through this test, the viscosity properties of Glass near the softening temperature can be obtained, thus providing important reference data for the manufacture, molding and application of Glass. This method is widely used in the fields of Glass production, scientific research and quality control to ensure the Stability and performance of Glass materials during processing.
