This standard is equivalent to the United Nations Food and Agriculture Organization FAO)202/1/* (1937 Oxymetholone Standard) and is based on the Chemical Industry Standard CS30G-1930 Dimethoate Technical Code One, and is revised in combination with the actual situation of domestic production The main technical difference between the six standards and HG3355-15 is: the addition of "precursor".
The technical indicators have been adjusted as follows: the first-class product standard, the content of oxydemeton-methyl is 92.0%, the moisture is less than or equal to 6.2%, and the acidity is less than or equal to 0.5%; the first-class product index, the content of oxydemeton-methyl is increased from greater than 710% to greater than 80.0%, and the moisture is adjusted from less than 3.5% to less than 0.3%; the qualified product index, the content of oxydemeton-methyl is increased from greater than 5.0% to 76.34.
The determination of the content of oxydemeton-methyl is determined by the retention layer method: the addition of The high performance phase chromatography method was adopted, which is equivalent to the method of the International Cooperation Council for the Analysis of Ingredients (CIIAC)>202/TC/M/-. The special test age was added, and the rounded value comparison method was adopted for the treatment of the limit effect. The "… The current inspection rules" were introduced in 2011, and its main contents "sampling" and "age rules" were placed at the beginning and end of the "test method" chapter: "safety" and "life" were added. This standard will be implemented from the month of implementation, and will be the same as HG product E-93.
