GB 22604-2008Tebuconazole emulsion, oil in water (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document replaces GB/T 22604-2008 "Tebuconazole Water Emulsion". Compared with GB/T 22604-2008, the only changes are structural adjustments and editing.

Aside from the sexual alterations, the main technical changes are as follows.

---The technical specifications for the tebuconazole mass fraction in the 12.5% specification have been revised (see 4.2, 3.2 in the 2008 edition);

---The technical specification for the mass concentration of tebuconazole in the 12.5% specification has been added (see 4.2);

---The technical specifications for pH have been changed (see 4.2, 3.2 in the 2008 edition);

---The technical specifications for sustained foaming properties have been changed (see 4.2, 3.2 in the 2008 edition);

---The technical specifications for dumping residue in dumping tests have been revised (see 4.2, 3.2 in the 2008 edition);

---The technical specifications for thermal storage stability have been revised (see 4.2, 4.8 in the 2008 edition);

---The gas chromatography method for the determination of tebuconazole mass fraction has been modified, and gas chromatography is now the arbitration method (see 5.5.1, 2008 edition).

(4.3.2)

---Product inspection and acceptance have been removed (see 4.10 in the 2008 edition);

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

---An acceptance and quality guarantee period has been added (see Chapter 7);

---Safety and warranty periods have been removed (see 5.5 and 5.6 of the 2008 edition).
