zwickiLine for Flexible Low-Force Testing.
The break resistance of injection needles is determined to DIN EN ISO 9626 (Annex D) using a 2-point flexure test. The needle is held on one side and the free side is bent at a defined angle.
To test the stiffness of the needle tubing to DIN EN ISO 9626 (Annex C), a 3-point flexure test kit is used. A defined flexure separation that corresponds to the needle gauge must be selected.
