The document specifies requirements for rubber and plastics hoses and hose assemblies for use with compressed or liquefied gases up to a maximum design pressure of 450 bar (45 MPa), within the ambient temperature range - 20 °C to + 60 °C. The document is applicable to high pressure hose assemblies to connect, without pressure regulators, the industrial gas cylinders or bundles to manifolds. It does not apply to refrigerated liquefied gases, or to LPG (Liquefied Petroleum Gases).
