Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 621-1993 "Chemicals hydrobromide", compared with the GB/T 621-1993 Technical changes are as follows.
--- Increasing the free bromine (see Chapter 4, 5.5);
--- Cancel the chroma (see 1993 edition of the 3.2,4.2);
--- 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 R66
"Hydrobromide" preparation, and ISO 6353-3. 1987 is equivalent to the degree of non-uniformity.
