Formulation Research and Interpretation of National Standard of GB/T 37635-2019
In this paper,the national standard of GB/T 37635-2019"textiles—test method for fatigue resistance on visual change of elastic straps"was interpreted.The application scope and test principle of the standard were emphatically introduced.The test parameters such as sample size,tensile speed,tensile proportion,fatigue stretching times and appearance inspection interval period were studied,and then the test parameters were determined.And the test method was verified from two aspects of sample repeatability and laboratory comparison.The results show that the test method has good reproducibility,and this standard is of great significance to standardize the quality and unify the evaluation methods and standards of elastic straps for upstream and downstream enterprises.
