EN ISO 7291:2010

Gas welding equipment - Pressure regulators for manifold systems used in welding, cutting and allied processes up to 30 MPa (300 bar) (ISO 7291:2010)

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.

a) komprimierte Gase bis zu 30 MPa1) (300 bar);
b) gelöstes Acetylen;
c) verflüssigte Erdgase (LPG);
d) Methylacetylen-Propadien-Gemische (MPS);
e) Kohlenstoffdioxid (CO2).
Sie gilt nicht für unmittelbar an Gasflaschen montierte Druckregler nach ISO 2503 [2].

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) (ISO 7291:2010)

L'ISO 7291:2010 spécifie les exigences et les méthodes d'essai relatives aux détendeurs de centrale de bouteilles utilisés pour le soudage, le coupage et les techniques connexes, pour: a) les gaz comprimés jusqu'à 30 MPa (300 bar); b) l'acétylène dissous; c) les gaz de pétrole liquéfiés (GPL); d) les mélanges de méthylacétylène-propadiène (MPS); e) le dioxyde de carbone (CO2).
Elle n'est pas applicable aux détendeurs directement fixés sur les bouteilles de gaz, tels que définis dans l'ISO 2503.

Oprema za plamensko varjenje - Glavni regulatorji tlaka plina za varjenje, rezanje in sorodne postopke za tlake do 30 MPa (300 bar) (ISO 7291:2010)

Ta mednarodni standard določa zahteve in preskusne metode za glavne regulatorje tlaka plina, ki se uporabljajo za: - stisnjene pline do 30 000 kPa (300 bar); - raztopljeni acetilen; - utekočinjene naftne pline (UNP); - metilacetilen-propadienove zmesi (MPS); - ogljikov dioksid (CO2); - za uporabo pri varjenju, rezanju in sorodnih postopkih. Ne velja za regulatorje tlaka, nameščene neposredno na plinske jeklenke, kot je opredeljeno v ISO 2503.
