ISO 21969:2005

High-pressure flexible connections for use with medical gas systems

Scope

ISO 21969:2005 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 these gases; air for driving surgical tools; nitrogen for driving surgical tools.
ISO 21969:2005 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.
It also 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.
