This standard is based on the specifications of the mancozeb sizing agent in the FAO coating drug specifications and combined with the actual domestic production This standard is revised from the chemical industry standard TIG3289-1952 Zineb Recyclable Test Agent. The main technical differences between this standard and HG3289-1982 are: 65% wettable powder specification is added: the control item of volume floating rate is added, and the daily index is greater than or equal to 50%, and the accelerated storage test is added: the original less than or equal to 1.0min is changed to less than or equal to 2.0min when the moisture is shown: the pH value is changed from ~ to 5.0~9., which is consistent with the FAO standard. This standard will replace HG3289-1982 from the date of implementation. This standard is proposed by the Technical Supervision Department of the former Ministry of Chemical Industry of the People's Republic of China, and this standard is under the jurisdiction of the Tongyang Chemical Research Institute. The unit responsible for the change of the standard is Shenyang Pesticide Factory. The main drafters of this standard are Xu and Shang. This standard was first issued in December 1965. This is the second revision. The Secretariat of the National Agricultural Standardization Technical Committee is responsible for the revision: s.

The sample is decomposed in the sulphur wave to generate magnetic sulphide and hydrogen sulfide gas, which is then absorbed by acetic acid, followed by the absorption of ethyl sulfide and the production of potassium disulfide. The ethyl sulfide is neutralized by titration with standard solution, the formula is: C,H,N,4H2O+NHE[,CII.NII)-HS,+2CS.+2.*S-CH.OK C,H,OCSSK
