Preface: This international standard and international standard ISO1352:1977 (E) the metal torsional stress fatigue test method of degree of consistency is not equivalent. Instead of this standard GB/T12443-1990 metal room temperature torsion stress fatigue test method, compared with the main changes are as follows: - increases the sign of torsion fatigue limit ; - in chapter 5, the redraw figure 2; - to cancel the requirement for testing machine frequency range adjustable; - modify the test report content; - on the part of the article chapter editorial changes. This standard put forward by the China iron and steel association. This standard by the national standardization technical committee under centralized steel. This standard drafting unit: iron and steel research institute, jinan times assay instrument co., LTD. Main drafter of this standard: liu tao, coef ophir, LuJianZhou. This standard replaced all previous releases of standard: GB/T12443-1990.   
Description:This standard specifies the principle of the torsional stress fatigue test of the metal material, terminology, symbols, sample, testing machine, test conditions, test procedures and test reports, etc.
