1.1 This International Standard applies to high-pressure flexible connections intended to be connected to
cylinders or cylinder bundles with nominal filling pressures up to 25 000 kPa at 15 °C for use with the following
medical gases:
? oxygen;
? nitrous oxide;
? air for breathing;
? helium;
? carbon dioxide;
? xenon;
? mixtures of the gases listed above;
? air for driving surgical tools;
? nitrogen for driving surgical tools.
1.2 This International Standard applies to high-pressure flexible connections intended to connect cylinders
or cylinder bundles to manifolds within sources of supply of medical gas pipeline systems complying with
ISO 7396-1.
1.3 This International Standard applies to high-pressure flexible connections intended to connect a cylinder
to an inlet port of medical equipment (e.g. anaesthetic workstation or lung ventilator) fitted with an integral
pressure regulator complying with ISO 10524-1.
1.4 This International Standard does not apply to high-pressure flexible connections intended to be used to
fill cylinders nor does it apply to low-pressure flexible hose assemblies that are covered by ISO 5359.
