Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 10120-1996 "metal stress relaxation test method", the content of the original standard techniques in the following aspects of the Great changes and additions. --- Modify the standard name; --- Modify the normative references; --- Modify the test principle, terminology, symbols and diagrams; --- An increase of two categories of tests. continuous and discontinuous test test, and "break test" to re-start the test requirements and step; --- Using EN10319-1.2003 Figure on tensile specimens relaxation offered to cancel the original standard tensile specimens FIG relaxation; --- Provisions of the coaxial test machine should not exceed 10%; --- Temperature range of the subdivision; --- Increased the tester changes in ambient temperature requirements; --- Calibration cycle temperature measuring device in detail provisions; --- Ambient temperature measurement sample size gives a clear request; --- Increasing the elastic modulus measurement requirements; --- Added "rounding off the test results" clearly requires the revision of the test results, delete the "Data Processing" Terms and content; --- Delete the original standard in Appendix A "prestressing steel tensile stress relaxation test specimen, test procedures and data processing"; --- Original standard body of the "cyclic bending stress relaxation test specimen, test procedures and data processing" as Appendix A; --- Increase the informative Appendix B "on different thermocouple materials"; --- Increase the informative Appendix C "thermocouple calibration requirements"; --- Increased by reference. This standard uses redrafted law revision adopts EN10391.2003 "metallic materials - Tensile stress relaxation testing - Part 1. Test program". This standard and EN10391. Difference and Its Cause 2003 is as follows. --- Delete the European Standard Introduction to adapt our standards to prepare and format requirements; --- Modify the standard name to expand the scope of use, ease of application; --- Remove the reference to European standards, adapt our standards to prepare and format requirements; --- Modify the scope to enhance the applicability; --- Lead normative references were modified accordingly to adapt our standards to prepare and format requirements; --- Modify the requirements extensometer calibration cycle to improve the operability of the test; Maximum allowable temperature --- temperature gradient to "3,4,5" for demanding test, the maximum temperature gradients were controlled at "2,3, 3 ", in order to improve the operability of the test; --- Increasing the normative Appendix A "high temperature cyclic bending stress relaxation test specimen, test procedures and data processing" to provide more comprehensive and clear; --- The EN10391.2003 Information Appendix A, Appendix B corresponds to Appendix B, Appendix C, preparation and adaptation of standard version Type requirements. The standard proposed by China Iron and Steel Association. This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized. This standard was drafted.
