What are the standards for electronic tensile testing machines?

Electronic tensile testing machine execution standards: GB/T16491, GB/T1040, GB/T1041, GB/T8804.1-2, GB/T8808, GB13022
It is used to test various mechanical properties, such as compression load, tensile strength, tear strength, insertion force pull-out force, etc. If you add an extensometer, you can use to break elongation, constant force ductility, etc. It is a commonly used material testing machine.
