BS EN ISO 21969:2009

This standard BS EN ISO 21969:2009 High-pressure flexible connections for use with medical gas systems is classified in these ICS categories:

• 11.040.10 Anaesthetic, respiratory and reanimation equipment
• 23.040.60 Flanges, couplings and joints

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;

• oxygen-enriched air.

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.
