HG 3307—2000
This standard is based on the chemical industry standard HG33C71990640 foreign military dimethoate emulsifiable concentrate + combined with domestic and production actual revisions:
This standard has the main difference from HG33071U00. The "Foreword" is added.
For the total qualitative multiple of the emulsion, 500 times needs to be rounded to 200; The determination of dimethoate content in the one-to-one rate retains the layer dilution method as the arbitration method, and the high performance liquid chromatography method is used. This method is equivalent to the International Pesticide Analysis Cooperation Council (CIPAC) 202/TC/M/-Method 1 adds the following: "Inspection or verification by rounding off comparison method is adopted for the treatment of the limit value"; cancels the "Inspection rules" chapter, and incorporates its main contents "Sample" and "Inspection rules" into the beginning and end of the "Test method" chapter respectively. This standard is implemented from the date of implementation and replaces IG3337-199U.
