---Added 25%, 30% and 50% specifications of technical indicators (see 4.2);

---Changed the technical indicators of durable foaming (see 4.2, 3.2 of the 2012 version);

---Changed the pH value technical indicators (see 4.2, 3.2 of the 2012 version);

---Changed the thermal storage stability technical indicators (see 4.2, 3.2 and 4.11 of the 2012 edition);

---Changed the gas chromatography method for determining the mass fraction of tebuconazole (see 5.5.1, 4.4.2 of the 2012 version);

---Changed the arbitration method for the determination of the mass fraction of tebuconazole (see 5.5.1, 4.4.1 of the 2012 version);

---Deleted product inspection and acceptance (see 4.12 of the 2012 version);

---Added inspection rules (see Chapter 6);

---Added acceptance and quality assurance period (see Chapter 7);

---Deleted the density determination of suspension agents (see Appendix B of the 2012 version).
