Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 20693-2006 `` Aminoavermectin Original Drug ''. Compared with GB/T 20693-2006, this standard mainly
The technical changes are as follows.
--- Increased the methylamino avermectin benzoate mass fraction control project (see 3.2);
--- The mass fraction of avermectin was changed from not less than 79.1% to not less than 83.5% (see 3.2, 3.2 of the.2006 version);
--- Increased benzoic acid mass fraction control project (see 3.2);
--- Deleted the moisture control project (see 3.2, 3.2 of the.2006 edition);
--- Acetone insolubles changed from not higher than 0.5% to not higher than 0.2% (see 3.2, 3.2 of the.2006 edition);
--- Increased the determination of benzoic acid mass fraction (see 4.5);
--- Amino avermectin benzoate original drug acceptance period was changed from 1 month to 2 years for quality assurance (see 5.2,.2006 version 5.7).
This standard was proposed by the China Petroleum and Chemical Industry Federation.
This standard is under the jurisdiction of the National Pesticide Standardization Technical Committee (SAC/TC133).
