GB/T 22604-2025Tebuconazole 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)

1 Scope

GB/T 22604-2025 is the Chinese national standard on tebuconazole emulsion,oil in water, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2026. Classification: ICS 65.100.30, CCS G 25. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. 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, quality guarantee period, marking, labeling, packaging, and storage of tebuconazole water-based emulsions. The test method for tebuconazole water emulsion is described. This document applies to the quality control of tebuconazole water-based emulsion products.

Note. Other names, structural formulas and basic physicochemical parameters of tebuconazole are given in Appendix A.
