GSO ISO 2503:2010 Scope

ISO 2503:2009 specifies requirements for single or two-stage pressure regulators without flow-metering devices for connection to gas cylinders used for ?compressed gases up to 300 bar (30 MPa), ?dissolved acetylene, ?liquefied petroleum gases (LPG), ?methylacetylene?propadiene mixtures (MPS), and ?carbon dioxide (CO2), for use in welding, cutting and allied processes. It does not cover pressure regulators having a nominal outlet pressure p2 > 20 bar. ISO 2503:2009 also specifies requirements for single or two-stage pressure regulators with flow-metering devices for connection to gas cylinders used for ?compressed gases or mixtures up to 300 bar (30 MPa), and ?carbon dioxide (CO2),
