Foreword
This standard in Chapter 3, Section 5 is mandatory, the rest are recommended.
This standard was drafted in accordance with rules GB/T 1.1-2009 given.
This draft standard method using the reformed modified using FAO Specifications 333/EC (May2005) "Deltamethrin."
This standard and FAO specification "Deltamethrin" The main technical differences and reasons.
--- This standard is to control the moisture content ≤1.0%, FAO specifications not control the indicators, EC water is too high, it will affect product quality
The amount should be controlled;
--- the FAO controlling the pH range of 4.5 to 7.5, the standard control pH range 4.0 to 7.0. Deltamethrin in neutral and weakly acidic
Medium stable;
--- FAO specifications lasting foam control amount ≤50mL (after 1min), this standard does not control the indicators. EC lasting domestic product
A small amount of foam, does not affect the product.
