The technological changes are as follows.

— Content related to the uses, properties, molecular formula, and relative molecular weight of xenon has been removed from the scope (see Chapter 1, 2006 edition). Chapter 1);

— The line about grading has been deleted, a requirement for 99 9999% purity xenon has been added, a requirement for total impurity content has been added, and some other changes have been made.

Limits for impurity content (see Chapter 4, Chapter 3 of the 2006 edition);

— The requirements for xenon gas sampling and sampling safety have been changed (see Chapter 5, 4.1.2 of the 2006 edition);

— The method for calculating xenon purity has been changed (see 6.1, 4.2 in the 2006 edition);

— The method for determining the hydrogen content in xenon gas has been changed (see 6.2, 4.4 of the 2006 edition);

— The methods for determining the carbon monoxide, carbon dioxide, and methane content in xenon gas have been revised (see 6.2, 4.5 of the 2006 edition);

— The method for determining moisture content has been changed (see 6.3, 4.6 in the 2006 edition);

— Requirements for exhaust gas treatment have been added (see 6.4);

— The requirements of the inspection rules have been changed, and provisions for rounding off numerical values have been added (see 7.1);

— Added labeling requirements (see 8.2);

— Added requirements for accompanying documents (see 8.3);

— The regulations for packaging, filling, transportation, and storage have been changed, and requirements for liquid xenon have been added (see Chapter 9, 2006 edition). Chapter 5);

— Added safety information for xenon (see Chapter 10);

— The section on determining the content of nitrogen, oxygen, argon, krypton, nitrous oxide, and fluoride in xenon using helium ionization gas chromatography has been removed.
