This European Standard specifies test methods for kinking properties for single lumen catheters and medical tubing,
as presented for clinical use, when bent in a single plane. It is recognized that other forces e.g. twisting will influence
the behaviour of the product, but no standard test methods are yet available. It is also recognized that such tubing can
be used to transport liquids or gases. However, water is used as a standard test medium, as the purpose of this
standard is to ensure uniformity in the evaluation of tubing kink properties.
NOTE This method is designed for single-lumen tubing but can also be used for multi-lumen tubing. It should be ensured
that the bending is done in the worst case direction, unless this would not present a possible real life situation.
Diese Norm legt Prüfverfahren für die Knickeigenschaften von Kathetern mit Einzellumen und Schläuchen zur medizinischen Anwendung im gebrauchsfertigen Zustand fest. Zweck dieser Norm ist die Sicherung der Einheitlichkeit bei der Bewertung der Knickeigenschaften von Schläuchen.
