The document specifies in detail the technical requirements, inspection rules, acceptance standards, mass warranty period, as well as aspects such as marking, labeling, Encasement and storage and transportation of dimethylene emulsifiable concentrate. The test method of dimethylene emulsifiable concentrate is also described in the document. The specification is applicable to the occasion where quality control of dimethylene emulsifiable concentrate products is carried out. Appendix A provides the Miscellaneous name, structural formula and basic physicochemical parameters of dimethylene emulsifiable concentrate. The normative reference document section lists a series of standards related to pesticides, including pesticide moisture determination method, pesticide ph value determination method, pesticide emulsion Stability determination method, commodity pesticide acceptance rules, commodity pesticide sampling method, etc. The document does not define terms and definitions, but the technical requirements specify that the Appearance of dimethylpendimethylene emulsifiable concentrate should be a stable homogeneous liquid with no visible suspended solids or settling (crystallization) at room temperature. In terms of technical indicators, the document specifies that dimethylpendimethylene emulsifiable concentrate should meet the relevant requirements in Table 1. This specification is designed to ensure that the mass of dimethylpendimethylenone emulsifiable concentrate products meets the specified standards.
