d) Changed the technical requirements for hydrogen content (see Table 1, Table 1 of the:2016 edition);
e) Changed the carbon dioxide technical requirements (see Table 1, Table 1 of the:2016 edition);
f) Change the technical requirements for carbon monoxide (see Table 1, Table 1 of the:2016 edition);
g) Added technical requirements for oxygen content (see Table 1);
h) Delete the technical requirements for ammonia content (see Table 1 of the:2016 edition)
i) Delete the technical requirements for solid particles (see Table 1 of the:2016 edition);
j) Delete the water dew point technical requirements (see Table 1 of the:2016 edition);
k) Changed the inspection rules and sampling requirements (see Chapter 6, Chapter 5 of the:2016 edition);
l) Added the determination method of oxygen content (see 5:5);
m) The requirements for transportation, marking, storage, transportation and use have been changed (see Chapter 7, Chapter 7 of the:2016 edition):
