GB/T 41708-2022 specifies the measurement method for the resistivity of glass in the molten state, clarifying key requirements such as the measurement principle, sample preparation, test procedures, and result processing. Based on Ohm’s law, it applies an AC voltage to the glass at high-temperature molten state, measures the current flow, and calculates the resistivity in combination with the dimensions of the molten material, primarily for evaluating the electrical properties of molten glass. The test requires instruments and equipment such as a tube furnace, an LCR tester, a Type B armored thermocouple, and high-purity corundum I-shaped ceramic boats to precisely control temperature and testing conditions. This standard provides a unified technical basis for glass production, research and development, and quality inspection, ensuring the accuracy of performance evaluations for related products.
