Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 1614-2011 "Industrial Barium Carbonate", compared with GB/T 1614-2011, except for structural adjustments and editorial changes
In addition, the main technical changes are as follows.
---Changed the burning residue indicators of strontium carbonate, iron and hydrochloric acid insoluble matter (see 5.2, 4.2 of the.2011 edition);
--- Changed the granular sieve residue index in the fineness to be negotiated with the user (see 5.2, 4.2 in the.2011 edition);
---Increase the sodium index (see 5.2);
---Inductively coupled plasma emission spectrometry for the determination of strontium carbonate content has been added (see 6.4.2);
--- Deleted the combustion capacity method for the determination of total sulfur content (see 5.7.2 of the.2011 edition);
---Infrared absorption method for the determination of total sulfur content has been added (see 6.8.2);
---The method for the determination of sodium content has been added (see 6.10).
