IIG 3297.-201
The third and fifth parts of this standard are mandatory, and the rest are recommended. This standard is a derivative of the mandatory chemical industry standard IIC3297-159$triethyl solution. The main technical differences between this standard and HG3297-1180 are: the range of H2O is increased, the actual storage temperature of phosphite and the addition of the cooling control date, and the control date of the acid cost. The analytical method of triethylamine is equivalent to the International Pesticide Analysis Cooperation Committee (1FAC38+/WP/M/(19U3) method. Increase the pH range, industrial phosphorus salt and accelerated storage test determination method. This standard is issued by the former State Petroleum and Chemical Industry Bureau Policy and Regulations Department from the date of implementation. This standard is drafted by the National Pesticide Standardization Technical Committee 1. This standard is drafted by: Shenyang Chemical Industry Research Institute, and the participating units are: Shandong Dawei Pesticide Co., Ltd., Zhenjiang Jiangnan Chemical Plant. The main people of this standard are Zhang Bulong, Jie Yankun, and Gong Baojie. This standard was first issued as a professional standard in 1980, and was converted into a regulatory chemical industry standard in 1990 and renumbered as TIG. .297$8S.
This standard is managed by the National Standardization Technical Committee of the National Coatings Standardization Technical Committee.5.
