GB 3405-1989Petroleum benzene (English PDF)

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 3405-2011 "Petroleum Benzene". Compared with GB/T 3405-2011, except for structural adjustments and editorial changes, in addition, the main technical changes are as follows.

a) The scope has been changed (see Chapter 1, Chapter 1 of the 2011 edition);

b) The test methods for purity, toluene, non-aromatic hydrocarbons and 1,4-dioxane have been changed (see Table 1, Table 1 of the 2011 edition);

c) The color test method and arbitration test method have been changed (see Table 1, Table 1 of the 2011 edition);

d) The quality index of petroleum benzene-535 thiophene was changed from "report" to "<=1.0mg/kg", and the test method of petroleum benzene-535 thiophene content was changed.

Methods (see Table 1, Table 1 of the 2011 edition);

e) Added the bromine index quality index of petroleum benzene-535 (see Table 1);

f) "Total sulfur content" was changed to "sulfur content", and the test method and arbitration method were changed (see Table 1, Table 1 of the 2011 edition);

g) The test method for nitrogen content has been changed (see Table 1, Table 1 of the 2011 edition);

h) The test method for water content has been changed (see Table 1, Table 1 of the 2011 edition);

i) Added the quality index and test method of chlorine content (see Table 1);

j) Changes have been made to marking, packaging, storage, transportation and delivery acceptance (see Chapter 7, Chapter 6 of the 2011 edition);

k) Safety has been modified (see Chapter 8, Chapter 7 of the 2011 edition);

l) The determination method for trace thiophene in petroleum benzene has been changed (see Appendix A, Appendix A of the 2011 edition).
