Foreword
This standard replaces GB/T 7118-1999 "industrial potassium chloride."
This standard and GB/T 7118-1999 compared to the main changes are as follows.
--- Increasing the requirements and test methods for net contents;
--- Increased product traits, canceled the sensory index requirements;
--- Increased test methods "General Provisions";
--- Modify the test method of moisture content;
--- Modify the content of potassium chloride test methods;
--- Potassium chloride standardized industrial product labeling and packaging requirements.
The standard proposed by China National Light Industry Council.
This standard by the National Standardization Center Salt Lake sea.
This standard by the National Standardization Center is responsible for drafting the sea Salt Lake.
The main drafters of this standard. Tong Yun Kun, Zhao Yi, Ren Qing Dynasty.
This standard replaces the standards previously issued as follows.
