《GB/T 8979-2008纯氮、高纯氮和超纯氮》由TC206（全国气体标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
本标准代替ＧＢ／Ｔ８９７９―１９９６《纯氮》和ＧＢ／Ｔ８９８０―１９９６《高纯氮》。本标准规定了纯氮、高纯氮和超纯氮产品的技术要求、检验方法以及包装、标志、贮运、安全警示等。本标准适用于空气分离或经净化得到的气态或液态的纯氮、高纯氮和超纯氮，主要用作保护气、置换气、反应气等。本标准与ＧＢ／Ｔ８９７９―１９９６和ＧＢ／Ｔ８９８０―１９９６相比主要变化如下：
―――调整了规范性引用文件（本版的第２章，ＧＢ／Ｔ８９７９―１９９６的第２章和ＧＢ／Ｔ８９８０―１９９６的第２章）；
―――修改了纯氮、高纯氮的技术要求（本版的表１，ＧＢ／Ｔ８９７９―１９９６的表１和ＧＢ／Ｔ８９８０―１９９６的表１）；
―――修改了氢、氧、一氧化碳、甲烷的测定方法（本版的４．３，ＧＢ／Ｔ８９７９―１９９６和ＧＢ／Ｔ８９８０―１９９６的４．３、４．４、４．６）；
―――增加了氩含量的测定方法（本版的４．５）。

Scope

This standard specifies the technical requirements, inspection methods, packaging, marking, storage and transportation, safety warnings, etc. of pure nitrogen, high-purity nitrogen and ultra-pure nitrogen products. This standard applies to gaseous or liquid pure nitrogen, high-purity nitrogen and ultra-pure nitrogen obtained by air separation or purification, and is mainly used as protective gas, replacement gas, reaction gas, etc. Molecular formula: N₂ Relative molecular mass: 28.0134 (according to relative atomic mass in 2005)
