Testing of medical tubing is associated with catheters and external devices such as feeding tubes, dialysis machines, and intravenous therapy drips. Failure of the tubing can cause severe patient injury so mechanical testing is critical to prove device safety. Tubing tests include tensile strength and elongation break tests, flexibility tests, joint strengths of connector fittings, torque assessments of rotary luer connectors, taps, valves, and stopcocks and trackability tests of device delivery systems.
