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 22614-2008 "clethodim technical substance" and GB/T 22615-2008 "clethodim emulsifiable concentrate", and is consistent with Compared with GB/T 22614-2008 and GB/T 22615-2008, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

---Changed the mass fraction index of clethodim in clethodim technical material (see 4.2, 3.2 of GB/T 22614-2008);

---Deleted the acetone-insoluble items and indicators in clethodim technical material (see 4.2, 3.2 of GB/T 22614-2008);

---Changed the pH value index of clethodim technical material (see 4.2, 3.2 of GB/T 22614-2008);

---Added the technical indicators of clethodim parent drug (see 4.2);

---Added two specifications of clethodim EC, 30% and 35% (see 4.2);

---Changed the moisture index of clethodim EC (see 4.2, 3.2 of GB/T 22615-2008);

--- Added items and indicators of durable foaming properties in clethodim EC (see 4.2);

---Changed the normal phase high performance liquid chromatography method (arbitration method) for the determination of clethodim mass fraction (see 5.5.1, GB/T 22614-2008 and 4.3 of GB/T 22615-2008);

---Changed the reversed-phase high-performance liquid chromatography method for the determination of clethodim mass fraction (see 5.5.2, GB/T 22614-2008 and Appendix A of GB/T 22615-2008);

---Deleted the method for determination of acetone insoluble matter in clethodim technical material (see 4.6 of GB/T 22614-2008);

---Deleted the acceptance period of clethodim technical material (see 5.7 of GB/T 22614-2008);

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

---Increased the quality assurance period of clethodim technical material (see 7.2).
