Scope: This document specifies the terms and definitions, model and nomenclature, structural composition, basic parameters, basic requirements, technical requirements, test methods, inspection rules, markings, and packaging of vacuum pressure swing adsorption oxygen generation equipment (hereinafter referred to as "oxygen generation equipment") , transportation and storage and quality commitment. This standard is applicable to equipment that uses molecular sieve vacuum pressure swing adsorption method to separate and produce oxygen from the air at room temperature. The oxygen production output is not more than 15 000 m3/h and the maximum working pressure is less than 0.1 MPa. Note 1: The oxygen production in this standard is in the standard state, that is, the gas volume at 0 ℃, 0.101 325 MPa (absolute pressure), in cubic meters (m3). Note 2: Unless otherwise noted, pressure values are gauge pressure values.
