GB/T 22602-2025Tebuconazole technical material (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 22602-2008 "Tebuconazole Technical Grade". Compared with GB/T 22602-2008, the main differences are structural adjustments and editorial changes. Aside from the modifications, the main technical changes are as follows:

---The technical specification for the mass fraction of tebuconazole has been changed (see 4.2,

3.2 in the.2008 edition);

---The technical specifications for moisture content have been changed (see 4.2,

3.2 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 section

4.7 of the.2008 edition);

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

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

---Security and acceptance periods have been removed (see

5.6 of the.2008 version). Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents.

1 Scope

GB/T 22602-2025 is the Chinese national standard covering tebuconazole technical - the assay by chromatography, the impurity profile, the moisture and the acidity, and the appearance, for one of the most widely used triazole fungicides. Issued on 31 October 2025, it has been in force since 1 May 2026, replacing GB/T 22602-2008.

This document specifies the technical requirements, inspection rules, acceptance procedures, and quality guarantee period for tebuconazole technical grade, as well as its marking, labeling, packaging, and storage. The test method for tebuconazole technical grade is described. This document applies to the quality control of tebuconazole technical grade products.

Note. Other names, structural formulas and basic physicochemical parameters of tebuconazole can be found in Appendix A.
