Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 650-1993 "chemical reagents potassium bromate," compared with the GB/T 650-1993 Technical changes are as follows.
--- Increasing the drying loss (see Chapter 4, 5.6);
--- Improve the sulfate determination (see 59, 1993 edition of the 4.3.5.);
--- Modify the packaging and logo (see Chapter 7, Chapter 6, 1993 edition).
The standard reference method using redrafted ISO 6353-3. 1987 "Reagents for chemical analysis - Part 3. Specifications 2 Series" in R75
"Potassium bromate" preparation, and ISO 6353-3. 1987 is equivalent to the degree of non-uniformity.
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee Chemistry (SAC/TC63) centralized.
This standard was drafted. Sinopharm Chemical Reagent Co., Ltd.
Units involved in the drafting of this standard. Test Reagent Co., Ltd. Taicang Shanghai.
The main drafters of this standard. Chenhao Yun, Zheng Qi, Gu Yan, Wang Wei.
This standard replaces the standards previously issued as follows.
--- GB/T 650-1965, GB/T 650-1977, GB/T 650-1993.
