GB/T 41641-2022 specifies in detail a test method for tensile testing of REBCO (Rare Earth Barium Copper Oxide) superconducting tapes at room temperature. This standard is primarily applicable for measuring the elastic modulus and the 0.2% proof strength of superconducting tapes, while also providing reference methods for determining parameters such as the elastic limit and fracture strength. The standard covers samples of superconducting tapes with a rectangular cross-section, where the cross-sectional area ranges from 0.12 mm² to 6.0 mm². The core testing instruments required for conducting tests according to this standard mainly include a tensile testing machine and an extensometer that meet the specified requirements. Among these, the testing machine must be capable of providing a constant crosshead displacement rate, and the mass of the extensometer typically needs to be controlled (e.g., not exceeding 30 grams) to avoid affecting the mechanical properties of the superconducting tape itself.
