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 for standardization documents"
Drafting.
This document replaces GB/T 18825-2002 "Industrial Cyclopentane". Compared with GB/T 18825-2002, except for structural adjustment and editing,
In addition to the changes in performance, the main technical changes are as follows.
a) The scope has been changed (see Chapter 1, Chapter 1 of the.2002 edition);
b) Added product classification (see Chapter 4);
c) Added technical requirements for coal-based cyclopentane (see Table 1);
d) The index of "petroleum-based cyclopentane" has been changed (see Table 1, Table 1 of the.2002 edition);
e) Added the method for determining density (see 5.3);
f) The determination methods of main content and impurity components have been changed, and the determination method of naphthalene has been added (see 5.4, 4.2 and 4.3 of the.2002 edition);
g) The determination method of moisture content has been added to GB/T 6324.8 (see 5.5);
h) GB/T 6324.10 is added to the determination method of sulfur content, and GB/T 6324.10 is used as the arbitration method (see 5.6).
