Foreword
This standard in Chapter 3, Section 5 is mandatory, the rest are recommended.
This modification uses standard FAO Specification 417/EC/S/F (1991) "carbosulfan EC" (in English).
This standard modification method using foreign advanced standards for the redrafted law.
This standard and FAO specification "carbosulfan EC," the main technical differences.
1) The standard carbosulfan EC in two sizes, 20% of the mass fraction is 20.0 + 1.2-1.2,200g/L is the mass fraction
21.0 + 1.2-1.2, the concentration is 200 + 12-12, FAO specifications no specific concentration of emulsifiable concentrates, only the marked content ≤500g/kg
The ± 5% emulsifiable concentrate of a predetermined fluctuation range, i.e., allow a marked content.
2) The standard control carbofuran impurity content is ≤0.5%, FAO specification is not larger than the content of carbosulfan measured
2%.
3) The standard moisture target of ≤0.5%, while the FAO specifications for ≤2g/kg (≤0.2%).
4) the actual situation overall quality of our products, pH values ranging from 7.0 to 9.0, while the FAO specification alkalinity indicators ≤1g/kg
(≤0.1%).
