b) The technical requirements of TA1 and TA2 products have been changed, and TA3 and TA4 have been deleted (see Table 5 and Table 6, Table 1 and Table 2 of the 2012 edition);

c) Added technical requirements for TA0, TA1G, TA2G, TA3G, TA4G products (see Table 1, Table 5, Table 6);

d) Changed the specification range of the product (see Table 1, Table 1 of the 2012 edition);

e) Changed the external dimensions and their allowable deviations (see 5.2, 3.5 of the 2012 edition);

f) Changed the bending performance requirements (see 5.4, 3.4 of the 2012 edition);

g) Changed the appearance quality requirements (see 5.4, 3.6 of the 2012 edition);

h) The analysis method of chemical composition has been changed (see 6.1, 4.1 of the 2012 edition);

i) The test method for tensile properties at room temperature has been changed (see 6.3, 4.2 of the 2012 edition);

j) Changed product marking requirements (see 8.1, 6.1 of the 2012 edition);

k) The packaging requirements have been changed (see 8.2, 6.2 of the 2012 edition).
