Beschreibung
Zusammenfassung:	The present invention relates to a high-pressure hose having a pressure class of H70 according to DIN ISO 19880-5 and/or a burst pressure of at least 3500 bar, the hose having a layered structure comprising a barrier layer composed of PA9T, at least one strength support layer, and an outer layer formed of a polymeric material. Such high-pressure hoses are characterised by a property profile that is very favourable for use with hydrogen at high pressures. The present invention also relates to a method for manufacturing such hoses, tank-filling devices equipped with such hoses, and uses of corresponding high-pressure hoses for transferring hydrogen from a storage container to a tank.
