Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 16494-1996 "Xylene Chemicals", compared with the GB/T 16494-1996, the major technological change
as follows.
--- Acidity, alkalinity of the unit by the "mmol/100g" adjusted "mmol/g" (see Chapter 4, Chapter 4 of the 1996 edition);
--- Analytical specifications of sulfur compounds from the "0.006% (in terms of SO4)" to "0.003% (as S)", by the chemical pure specifications
"0.01% (in terms of SO4)" to "0.005% (as S)" (see Chapter 4, Chapter 4 of the 1996 edition);
--- Thiophene and its homologues specification by "0.0001%" to "qualified" (see Chapter 4, Chapter 4 of the 1996 edition);
--- Modify the method for the determination (see 52, 1996 version 5.1.);
--- Easy carbonized material increased standard colors (see 57, 1996 version 5.6.);
--- Modify the packaging and logo (see Chapter 7, Chapter 7 of the 1996 edition).
The standard reference method using redrafted ISO 6353-3. 1987 "Reagents for chemical analysis - Part 3. Specifications 2 Series" in R95
"Xylene" preparation, and ISO 6353-3. 1987 is equivalent to the degree of non-uniformity.
