Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 1397-1995 "chemical reagents potassium carbonate," compared with the GB/T 1397-1995 Technical Changes
as follows.
--- Standard name "potassium" to "anhydrous potassium carbonate";
--- Clarity test specifications by a "qualified" to "2", "3", "5" (see Chapter 4, 1995, version 3.2);
--- Project name "drying loss" to "loss on ignition" (see Chapter 4, 55, 1995 edition of 3.2,4.2.3.);
--- Adjust the amount of sodium sampling measurement (see 510, 1995 version 4.2.8.);
--- Modify the determination of iron (see 514, 1995 edition of 4.2.12.);
--- Improved copper, lead two of the measuring method (see 515, 517, 1995 edition 4.2.13,4.2.15.);
--- Adjustment packaging and signs (see Chapter 7, Chapter 6, 1995 edition).
