Gas welding equipment -- Pressure regulators for manifold systems used in welding, cutting and allied processes up to 30 MPa (300 bar)
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
ISO 7291:2010 specifies requirements and test methods for pressure regulators in manifold systems used in welding, cutting, and allied processes for: a) compressed gases up to 30 MPa (300 bar); b) dissolved acetylene; c) liquefied petroleum gases (LPG); d) methylacetylene‑propadiene‑mixtures (MPS); e) carbon dioxide (CO2).
It is not applicable to pressure regulators fitted directly to the gas cylinders, as defined in ISO 2503.
