This standard specifies the basic parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of fully oil-free lubricated high-pressure reciprocating piston oxygen compressors (hereinafter referred to as oxygen compressors). This standard is applicable to oxygen compressors with an inlet pressure of 0.002 MPa~0.4 MPa, a rated exhaust pressure of 15.0 MPa, and a nominal volume flow rate not greater than 100 m/h (standard state). Oxygen compressors that are not within the scope of this standard may be implemented with reference to this standard.
