c) Deleted the corresponding original digital grades and product grades "RESiFe-38Ce" and "RESiFe-41Ce" in the product grades (see:2015
Table 1 of the version);
d) Added product grades "RESiFe-30-LaC", "RESiFe-30-CeC", "RESiFe-32-LaC", "RESiFe-32-CeC"
“RESiFe-20-CeM”, “RESiFe-23-CeM” and “RESiFe-26-CeM” (see Table 1 );
e) Changed the product grades of light rare earth ferrosilicon alloy and the content requirements of their corresponding chemical components (see Table 1, Table 1 of the:2015 edition);
f) Changed the product grades of yttrium-based heavy rare earth ferrosilicon alloys and the content requirements of their corresponding chemical components (see Table 2,:2015 Edition):
1);
g) Added "If the purchaser has special requirements for the particle size range, it can be determined through negotiation between the supply and demand parties" (see 5:2);
h) Added the condition requirement of “under natural diffuse light” (see 6:3);
i) Added the provisions on the number of particle size sampling (see 7:4:2);
j) Changed the product packaging description from "sealed in iron drums with anti-oxidation measures" to "packaged in woven bags with plastic-sealed inner bags"
(see 8:1, 6:2 of the:2015 edition):
