--- Removed the profile, extreme dimensions and tolerances of the threaded 5CV (see 7.1 of the.2008 edition);
--- Revised Table 2 in "Installation Torque" (see Table 2, Table 2 of the.2008 edition);
--- Modified "torque performance" (see 9.2,.2008 version 10.1);
---Modified "core head position" (see 9.3,.2008 version 10.5);
--- Revised the "maximum operating pressure of the valve core" and "temperature range" (see 10.1, 10.2, Chapter 8 of the.2008 edition);
--- Added fatigue resistance requirements for "H01, H02 and H06C valve cores" (see 10.3);
--- Added "H01 type, H02 type and H06C type valve core" ventilation rate requirements (see 11.1);
--- Added corrosion resistance requirements for "H01, H02 and H06C valve cores" (see 11.2);
---Modified the "connection of the core cap to the core" (see 11.3, 10.2 of the.2008 edition);
--- Modified "rebound elasticity" (see 11.4, 10.3 of the.2008 edition);
--- Modified "opening pressure" (see 11.5, 10.4 of the.2008 edition);
--- Modified the "thread" and "core beam width" test methods (see 12.3 and 12.4,.2008 version 11.3);
--- Revised Table 3 in the "Inspection Rules" (see Table 3, Table 3 of the.2008 edition).
