Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 23934-2009 "hot coiled helical compression spring technical conditions." And GB/T 23934-2009 phase
Ratio, the main technical changes are as follows.
--- Adds symbols and units;
--- Modify the scope;
--- Modify the normative references;
--- Remove the structure type;
--- Increased spring structure;
--- Revised test methods.
This standard uses redrafted Law Amendment uses ISO 11891.2012 "hot rolled coil compression spring technical conditions."
This standard and ISO 11891.2012 as compared to the presence of the technical differences between the terms of these differences has been involved through its outer margin bits
Opposing vertical single line (|) were marked.
This standard and ISO 11891.2012 technical differences and their reasons are as follows.
--- Modify the normative references (see Chapter 2);
--- Modify the symbols and units (see Chapter 4);
--- Increased material GB/T 1222 selection (see 5.1);
--- Modifies the bar tolerances into GB/T 702-2008 (see 5.2);
--- Increase the permanent deformation (see 8.5,10.2);
--- Modify harmful defects (see 9.5);
--- Revised Figure 3 (see 10.4.3);
--- Added a test load calculation (see Appendix A);
--- Added a common spring steel tensile strength - hardness correspondence (see Appendix B).
