Preface
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 1606-2008 "Industrial Sodium Bicarbonate". Compared with GB/T 1606-2008, except for structural adjustments and editorial
In addition to the modifications, the main technical changes are as follows.
a) The product classification has been changed (see Chapter 5, Chapter 4 of the.2008 edition);
b) The indicator parameters have been changed and adjusted according to the new product classification (see 6.2, 5.2 of the.2008 edition);
c) Added the test method of chloride content potentiometric titration (see 7.4.1);
d) The test method for chloride content by visual turbidimetry has been deleted (see 6.7.2 of the.2008 edition);
e) Added the test method for iron content by inductively coupled plasma optical emission spectrometry (see 7.5.2);
f) Added the test method of barium sulfate gravimetric method for sulfate content (see 7.6.1);
g) Added the test method of water-insoluble matter content microporous filtration membrane method (see 7.7.2);
h) The test method for water-insoluble matter content using asbestos filter paper method has been deleted (see 6.9.5 of the.2008 edition);
i) The test method for arsenic content has been changed (see 7.11, 6.12 of the.2008 edition);
j) The test method for heavy metal content has been changed (see 7.12, 6.13 of the.2008 edition).
