High-pressure flexible connections for use with medical gas systems (ISO 21969:2009)
Abstract
ISO 21969:2009 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;
- oxygen-enriched air.
ISO 21969:2009 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.
ISO 21969:2009 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.
