Foreword

This standard replaces GB/T 11992-1989 "chlorine-type strongly basic anion exchange resin exchange capacity mensuration method." Compared with GB/T 11992-1989 standard version of this standard the following major changes occurred. --- Given two kinds of chlorine type strongly basic anion exchange resins Determination of exchange capacity. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee plastic universal methods and products Club (SAC/TC15/SC4) centralized. This standard is mainly drafted by. Xi'an Thermal Power Research Institute Co., Ltd., Jiangsu Su Qing water treatment engineering company, Zibo Dongda Chemical Stocks Parts Limited, winning glory Zhejiang Industrial Co., Ltd., the national quality inspection center of a synthetic resin. The main drafters of this standard. Wang Guang Zhu, Qian Ping, Cai Xiaohua, Di Jinghua, Shen Jianhua, Cuihuan Fang, Wang Jiandong. This standard replaces the standards previously issued as follows. --- GB/T 11992-1989. Chlorine type strongly basic anion exchange resin Determination of exchange capacity

1 Scope
