— Deleted the content related to the use, molecular formula and relative molecular mass of industrial nitrogen in the scope (see Chapter 1, 2008 edition Chapter 1);

— Increased requirements for 99.5% and 99.9% purity industrial nitrogen, and increased carbon monoxide content, carbon dioxide content, and moisture content and total impurity content requirements (see Chapter 4, Chapter 3 of the 2008 edition);

— Added requirements for industrial nitrogen batching (see 5.1);

— Changed the requirements for industrial nitrogen sampling and sampling safety (see 5.2, 4.1.2 of the 2008 edition);

— Changed the requirements for industrial nitrogen sampling (see 5.3, 4.1.3 and 4.1.4 of the 2008 edition);

— Changed the calculation method of nitrogen purity (see 6.1, 4.2 of the 2008 edition);

— Added the method for determining the content of carbon monoxide and carbon dioxide in nitrogen (see 6.2);

— Changed the method for determining the oxygen content in nitrogen (see 6.3, 4.3 of the 2008 edition);

— Changed the method for determining the moisture content in nitrogen (see 6.4, 4.4 of the 2008 edition);

— Added requirements for exhaust gas treatment (see 6.5);

— Changed the requirements for inspection rules and added provisions for numerical rounding (see Chapter 7, 4.1.3 of the 2008 edition);

— Changed the labeling requirements (see 8.2);

— Added requirements for accompanying documents (see 8.3);
