This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage requirements for pesticide emulsifiers composed of surfactants and appropriate solvents.
This standard applies to various types of special mixed emulsifiers used in the processing of pesticide emulsifiable concentrates. 2 Reference Standards
GB3776.3 Determination Method for Emulsification Performance of Pesticide Emulsifiers GB/T6368 Determination of pH Value of Surfactant Water Solvent Potentiometric Method GB/T7380 Determination of Water Content of Surfactant Karl Fischer Method 3 Technical Requirements
Various pesticide emulsifiers should meet the technical requirements in the following table. Item
Appearance (20℃)
Water content\, %
pH value (1% aqueous solution)
Emulsification stability after preparing pesticide emulsifiable concentrate
Appearance of emulsifiable concentrate

, no floating oil on the top, no precipitation below
Note: 1) When preparing pesticide emulsifiable concentrate with pesticide emulsifier, there are 4 water indexes of emulsifier ≤0.3%; ≤0.4%; ≤0.5%; ≤1.5%. Each index corresponds to the type of pesticide emulsifiable concentrate to be prepared. For the same type of pesticide emulsifier, multiple pesticide emulsifiable concentrates can be prepared, and its water index should be based on the lowest water content.
For pesticide emulsifiers, see Appendix B (reference). 4 Test methods
4.1 Appearance determination: visual inspection at 20°C.
4.2 Determination of water content: in accordance with the provisions of GB7380. 4.3 Determination of pH: in accordance with the provisions of GB6368. 4.4 Determination of emulsification performance: in accordance with the provisions of GB3776.3. A certain emulsifier is used to prepare a specified pesticide emulsifiable concentrate, and the stability of its emulsion is determined. The specified test conditions are shown in Appendix A (supplement). 5 Inspection rules
5.1 Pesticide emulsifiers should be inspected by the quality inspection department of the manufacturer. The manufacturer should ensure that all products shipped meet the requirements of this standard approved by the Ministry of Chemical Industry of the People's Republic of China on July 5, 1993 and implemented on January 1, 1994
HG/T2466-93
. Each batch of pesticide emulsifiers shipped should be accompanied by a quality certificate. 5.2 The pesticide emulsifier is a batch based on the uniform finished product mixing tank capacity, and samples of each batch should be kept for reference. 5.3 Sampling method: Sampling is based on 5% of the total number of barrels of pesticide emulsifier. The minimum number shall not be less than 3 barrels. Use a clean and dry glass tube to take out a representative sample of no less than 100g from each barrel and put it into a clean, dry, stoppered sample bottle. The bottle is labeled and marked with: manufacturer name, product name, model, batch number, sampling date. 5.4 Users can conduct inspections according to this standard within one week after receiving this product. If one indicator in the inspection results does not meet the requirements of this standard, the sample should be doubled and re-sampled. The results of the re-inspection, even if only one indicator does not meet the requirements of this standard, the entire batch of products cannot be accepted. 5.5 When the supply and demand parties have a dispute over the quality of this product, the two parties can negotiate to resolve it or select an arbitration agency to conduct arbitration inspections according to the methods specified in this standard.
6 Marking, packaging, transportation, storage
6.1 Marking
Each barrel of packaged products should have a clear and firm mark. The content includes: manufacturer name, trademark, product name, model, batch number, net weight, production date, this standard number and quality certification mark. 6.2 Packaging
Pesticide emulsifiers are packaged in clean, dry, sealed, leak-proof galvanized iron barrels. The net weight of each barrel is 100kg or 200kg. 6.3 Transportation
During transportation, it must be protected from moisture, rain, exposure and collision. 6.4 Storage
During storage, it must be protected from sunlight, rain and fire. The pesticide emulsifier has a warranty period of 1 year from the date of delivery. 236
