《GB/T 8980-1996高纯氮》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。
本标准规定了高纯氮产品的技术要求、检验方法以及包装、标志等。
本标准适用于由空气分离制取的高纯度气态或液态氮，其化学性质不活泼，不可燃，是一种窒息性气体，主要用于科学研究、标准混合气制备、保护气、置换气、载气、反应气等对氮气纯度要求高的领域。
分子式 : N2
相对分子质量:28.0134(按1991年相对原子质量)。

Scope

This standard stipulates the technical requirements, inspection methods, packaging and signs of high-purity nitrogen products. This standard applies to high-purity gaseous or liquid nitrogen produced by air separation. Its chemical properties are inactive and non-flammable. It is an asphyxiating gas and is mainly used for scientific research, preparation of standard mixed gas, protective gas, replacement gas, Carrier gas, reaction gas and other fields that require high nitrogen purity. Molecular formula: N₂. Relative molecular mass: 28.0134 (according to relative atomic mass in 1991).
