GB/T 22605-2025Tebuconazole emulsifiable concentrate (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 22605-2008 "Tebuconazole Emulsifiable Concentrate". Compared with GB/T 22605-2008, the main differences are structural adjustments and editorial changes. Aside from the modifications, the main technical changes are as follows:

---The technical specifications for the.200g/L specification have been added (see 4.2);

---The technical specification for sustained foaming performance has been added (see 4.2);

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

3.2 in the.2008 edition);

---The technical specifications for pH have been changed (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 section

4.9 of the.2008 edition);

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

1 Scope

GB/T 22605-2025 is the Chinese national standard on tebuconazole emulsifiable concentrate, in the field of agriculture.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

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

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