　　High-purity air is a mixture of high-purity oxygen and high-purity nitrogen, in which the proportion of nitrogen and oxygen is the same as that of natural air. High purity air is also called zero air or zero grade air.

　　High purity air is widely used as combustion gas in gas chromatographs, gas chromatographs and atomic absorption spectrometers, and is also used to calibrate the zero point of analytical instruments.

　　This document specifies the terms and definitions of high-purity air, describes the preparation methods and test methods of high-purity air, establishes the inspection rules, and specifies the technical requirements, marks, packaging, storage and transportation and safety information requirements of high-purity air.

　　This document is applicable to high-purity air prepared from high-purity oxygen and high-purity nitrogen.
