Chapter 3 of the year edition);
e) Changed the inspection rules (see Chapter 5, 4.1 of the.2009 edition);
f) Added the specific content of sampling (see Chapter 6, Appendix A);
g) The determination method of oxygen content has been changed (see 7.2, 4.3 of the.2009 edition);
h) The specific description of the determination of hydrogen content, nitrogen content and carbon monoxide content is deleted, and it is changed to be carried out according to the provisions of GB/T 28726 (see
7.3, Appendix A of the.2009 edition);
i) Changed the determination method of total hydrocarbon content (see 7.4, 4.5 of the.2009 edition);
j) Modified the determination method of moisture content (see 7.5, 4.6 of the.2009 edition);
k) Changed the signs, packaging, storage and transportation, filling and safety warnings (see Chapter 8, Chapter 5 of the.2009 edition);
l) The schematic diagram of the chromatographic gas circuit for the determination of total hydrocarbon content is added (see Appendix B);
