Compliance overview
Scope and applicability
This standard applies to 35% Isocarbophos emulsifiable concentrates formulated from isocarbophos technical and emulsifiers dissolved in suitable solvents. It is specifically designed for agricultural pesticide products and does not apply to other concentrations or formulations of isocarbophos. Manufacturers of organophosphorus insecticides must ensure their products meet these specifications.
Technical requirements
The standard specifies the physical and chemical requirements for the emulsifiable concentrate, ensuring product stability and efficacy. Key parameters include the active ingredient content, water content, and acidity limits. The product must appear as a stable homogeneous liquid without visible suspended matter or precipitates. Compliance with these technical indicators is mandatory for market access. Additionally, the standard outlines requirements for low-temperature and thermal storage stability, ensuring the product maintains its integrity under various environmental conditions. It also mandates specific packaging, labeling, and safety protocols, referencing GB 4838 for pesticide packaging.
Testing methods
To verify compliance, the standard prescribes several analytical methods. The active ingredient content is determined using High-Performance Liquid Chromatography (HPLC) as the arbitration method, or alternatively, Gas Chromatography (GC). Water content is measured using the Karl Fischer method (referencing GB/T 1600). Emulsion stability is tested by diluting the sample 200 times, while low-temperature and thermal storage stabilities are evaluated according to GB/T 19137 and GB/T 19136, respectively. These tests must be conducted periodically during normal production.
