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 34333-2017 "Analysis Method of Refractory Materials by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES)"
Compared with GB/T 34333-2017, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) The scope of application has been changed, 16 analytical items such as Li2O and their applicable measurement ranges have been added, and the scope of K2O and Na2O has been expanded.
Determination range, the method detection limit of each test item is given (see Chapter 1, Chapter 1 of the.2017 edition);
b) Deleted the requirements for inductively coupled plasma atomic emission spectrometers (see 3.1 of the.2017 edition);
c) Added requirements for reagents and test water (see 5.1);
d) Added the allowable deviation requirement for analytical values when the content is less than or equal to 0.1% (see 5.5.2);
e) Added requirements for sample preparation tools, equipment and media (see 7.2.3);
f) Added the provisions on reagents (see Chapter 8);
g) Deleted the provisions on optimization of instrument working conditions (see Chapter 9 of the.2017 edition);
h) Added the types and methods of preparing standard solutions (see Chapter 9);
i) Added the types and methods of preparing matrix solutions (see Chapter 10).
