ISO 14113:2013
Gas welding equipment — Rubber and plastics hose and hose assemblies for use with industrial gases up to 450 bar (45 MPa)
ISO 14113:2013 specifies requirements for rubber and plastics hose and hose assemblies for use with compressed, liquefied, and dissolved gases up to a maximum working pressure of 450 bar (45 MPa), within the ambient temperature range of −20 °C to +60 °C.
It applies to hose assemblies used to connect industrial gas cylinders to manifolds or bundles prior to any pressure reduction stage. It does not cover rubber or thermoplastic hoses for welding, cutting, and allied processes (see ISO 3821 and ISO 12170). It does not apply to refrigerated liquefied gases or to liquefied petroleum gases (LPG).
