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 320-2006 "Synthetic hydrochloric acid for industrial use". Compared with GB/T 320-2006, except for structural adjustments and editorial changes,
In addition to the modifications, the main technical changes are as follows.
a) Product quality classification has been deleted (see 3.2 of the.2006 edition);
b) The technical requirements for industrial synthetic hydrochloric acid products have been changed (see 4.2, 3.2 of the.2006 edition);
c) Added the number of samples (see 5.2.3);
d) The method for determining arsenic content has been deleted (see 5.6 and 5.7 of the.2006 edition);
e) Added potentiometric titration method for determining total acidity (see 6.3.2);
f) The mass concentration of the iron standard solution in the spectrophotometric determination of iron content (see 6.4.1.2.6, 5.3.2.6 of the.2006 edition) and
Addition amount (see 6.4.1.4.1.1, 5.3.4.1.1 of the.2006 edition);
g) Added ICP method for determination of iron content (see 6.4.2);
h) The concentration of sodium thiosulfate standard titration solution in the determination of free chlorine content has been changed (see 6.6.2.2, 5.5.2.2 of the.2006 edition);
i) In “Determination of mass fraction of sulfate”, the following is added. “When the absorbance of the sample exceeds the maximum absorbance value of the curve, the
Re-measure the sample volume so that the absorbance is within the range of the standard curve” (see 6.7.4.4.3);
j) The inspection rules have been changed (see Chapter 7, Chapter 6 of the.2006 edition);
k) The marking has been changed (see 8.1, 7.1 of the.2006 edition);
l) Added accompanying files (see 8.2);
m) Transport and storage have been modified (see 9.2, 9.3, 7.3, 7.4 of the.2006 edition).
