Foreword
This standard replaces GB/T 10128-1988 "metal room temperature torsional test method", compared with the changes as follows.
--- In the normative references delete the original reference standard GB 6397 "metal tensile test specimen", an increase of GB/T 10623
"Terminology of mechanical properties test of metallic materials", JJG269 "Torsion testing machine";
--- In the "terminology, symbols" chapter, the terms in accordance with GB/T 1.1-2000 rewritten, the "yield point" to "yield strength
Degree "," on the yield point "to" on the yield strength "," under the yield point "to" under the yield strength "; delete the original standard Table 1 symbols
Number "τs";
--- In Chapter 5 added "Figure 2 tubular sample plug";
--- Torsion meter requirements have been modified;
--- Modify the reverse speed;
--- The yield point, the yield point and the lower yield point of determination was changed to "on the yield strength and yield strength measured", while deleting
Formula (7) in GB/T 10128-1988;
--- In the performance test increased the use of automatic device measured content;
--- Modify the formula (11) in GB/T 10128-1988;
--- Modify the value of the revised paragraph about repair;
--- The contents of the test report has been supplemented.

Mechanical properties.
4 Terms, definitions and symbols
4.1 Terms and definitions
The terms specified in GB/T 10623 and the following terms and definitions apply to this standard.
4.1.1
L0
The length of the distance between two marks used to measure the twist angle on the specimen.
4.1.2
The length of the parallel part of the specimen used to measure the torsion angle of the specimen shall be measured with a twisting meter.
4.1.3
The maximum torque that the specimen can withstand after the yield phase. For no obvious yield (continuous yield) metal material, during the test
The maximum torque.
4.1.4
The ratio of shear stress to shear strain varies linearly with shear stress.
