GB/T 34217-2017 "Refractory Products—Test Method for High-Temperature Torsional Strength" specifies the test method for determining the torsional strength of refractory materials in high-temperature environments (typically ≥1000°C). By applying torque to a cylindrical specimen until it fractures, the torsional strength is calculated. This method is used to simulate and evaluate the ability of refractory components (such as kiln arches and corners) to resist torsional shear stress at high temperatures.
