Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 2093-1993 "industrial acid", compared with the GB/T 2093-1993, the main technical changes are as follows.
--- The products are divided into 94% according to different content, 90%, 85% three specifications (see Chapter 3), each size were divided into three equal
Level (see 42, 1993, version 3.2.);
--- Adjust the color, dilution test, chlorides, sulfates, iron and evaporation residue indicators (see 42, 1993, version 3.2.);
--- Test Method for increasing the appearance (see 5.3);
--- Increased chloride and sulfate content determination by spectrophotometry (see 5.7 and 5.8);
--- Modify the chlorides, sulfates, iron content and evaporation residue sampling method, the amount of volume is amended as weighed mass (see 5.7,
. 5.8,5.9 and 510, the 1993 edition of 4.4,4.5,4.6 and 4.7);
--- Increased security chapter (see Chapter 8);
--- Remove the acid and formic acid density measurement density meter (see the 1993 version of Appendix A and Appendix B).
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee on Organic Chemistry Chemical Technical Committee (SAC/TC63/SC2) centralized.
This standard was drafted. Feicheng Acid Chemical Co., Ltd.
Participated in the drafting of this standard. Chongqing East Sichuan Chemical Industry (Group) Co., Ltd.
The main drafters of this standard. Bao-away, Zhang Bingsheng, Chen Yanjun, Wu Feng, Liu Haitao, Wang Lu.
This standard was first published in 1980, in April 1993 the first amendment.
