Scope

GB/T 3864-2025 is the English-translated version of 工业氮.

GB/T 3864-2025 is the Chinese national standard covering nitrogen separated or purified from air, gaseous or liquid — the purity grades and the limits on oxygen, carbon monoxide, carbon dioxide and moisture, the batching and the sampling that has to be done without asphyxiating anyone, the determination methods for each impurity, the exhaust gas treatment, the inspection rules, the cylinder marking and accompanying documents, and the safety information for a gas that displaces air without warning.

It replaces GB/T 3864-2008, under the China Petroleum and Chemical Industry Federation. In force from 1 February 2026. Issued on 1 August 2025, it has been in force since 1 February 2026, replacing GB/T 3864-2008.
