GB/T 13465.10-2024 "Test Methods for Impermeable Graphite Materials - Part 10: Tensile Strength" is applicable to the determination of the tensile strength of impermeable graphite materials used in chemical production at both room temperature and high temperatures. It replaces the original relevant standards and introduces new procedures for high-temperature tensile testing. The testing requires the use of a universal material testing machine with the required precision, paired with high-temperature testing accessories that provide accurate temperature control. By preparing standard specimens, setting the testing rate (room temperature/high temperature), applying tensile force until the specimen fractures, recording the maximum load, and calculating the tensile strength, this standard provides a basis for the mechanical performance evaluation of impermeable graphite materials in selection and application.
