Foreword
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces the GB/T 10698-1989 "Expandable Graphite" standard: Compared with GB/T 10698-1989, except for structural adjustments and compilation
In addition to editorial changes, the main technical changes are as follows:
a) Changed the “scope” (see Chapter 1, Chapter 1 of the 1989 edition);
b) Added normative reference documents GB/T 6682 (see 6:3:1:5), GB/T 8170 (see 6:2:4, 6:3:3, 6:5:4, 6:7:5),
GB/T 24533 (see 6:8), GB/T 191 (see 8:1:1);
c) Changed "Terms and Definitions" (see Chapter 3, Chapter 3 of the 1989 edition);
d) Delete "product brand and grade" (see Chapter 4 of the 1989 edition);
e) Added “Classification and Labeling” (see Chapter 4);
f) Changed the "technical requirements" (see Chapter 5, Chapter 5 of the 1989 edition);
g) Changed "Sample Preparation" (see 6:1, 6:1 of the 1989 edition);
h) The test methods of "moisture content", "pH value", "swelling volume" and "ash content" have been changed (see 6:2, 6:3, 6:5, 6:7, 6:2, 6:4, 1989 edition)
6:5, 6:7);
i) “Determination of particle size” is deleted (see 6:3 of the 1989 edition);
j) Added the "sieve residue" test method (see 6:4);
k) Added the "sulfur content" test method (see 6:6) and deleted the "volatile matter determination" test method (see 6:6 of the 1989 version);
l) Added "fluoride ion and chloride ion" test method (see 6:8);
m) The inspection rules have been changed (see Chapter 7, Chapter 7 of the 1989 edition);
n) Changes in marking, packaging, transportation and storage (see Chapter 8, Chapter 8 of the 1989 edition):

Note: The unit is milliliters per gram (mL/g):
4 Classification and tagging
4:1 Classification
Expandable graphite is divided into two categories: high-sulfur expandable graphite and low-sulfur expandable graphite according to the sulfur content after expansion: After expansion of high sulfur expandable graphite
If the sulfur content (mass fraction) is greater than or equal to 0:120%, the code is KG: The sulfur content (mass fraction) of low-sulfur expandable graphite after expansion is less than
0:120%, codenamed KD:
4:2 Marking
The expandable graphite mark consists of the product name, this document number, and product code:
