GB/T 21921-2008 "Test Method for Tensile Strength of Impervious Graphite Materials" specifies the method for determining the tensile strength of impervious graphite materials (processed by impregnation and other techniques) at room temperature. A special fixture is used to apply tensile load to a dumbbell-shaped specimen until it fractures, and the tensile strength is calculated to evaluate the mechanical properties of this corrosion-resistant material when used as equipment components.
