Matériel de soudage aux gaz — Détendeurs de centrale de bouteilles pour le soudage, le coupage et les techniques connexes jusqu'à 30 MPa (300 bar)

Abstract / scope

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.
