Test di forza di sgancio e di scorrimento

In syringe performance evaluation, prova di forza di sgancio e di scivolamento plays a crucial role in assessing the smoothness and reliability of the plunger movement. This test determines the force required to initiate and maintain the motion of the syringe piston, ensuring consistent drug delivery and patient safety.

Cell Instruments, a leading manufacturer of materials testing equipment, provides advanced break loose and glide force testing machines designed according to Norma ISO 7886-1 standards. These instruments help manufacturers, laboratories, and quality control professionals ensure that their syringes meet international quality and performance requirements.

ISO 7886-1 and Syringe Performance

The international standard Norma ISO 7886-1 specifies the requirements and test methods for sterile hypodermic syringes for single use. Annex E of the standard outlines the test method for determining the forces required to operate the piston, including both rompere la forza E gliding force.

  • Break loose force refers to the initial force required to start the plunger movement.
  • Gliding force represents the continuous force needed to maintain piston movement throughout the stroke.

These two parameters are critical indicators of syringe quality, influencing user comfort, injection accuracy, and drug flow stability. Excessive or inconsistent forces can result in jerky movement, dosage errors, or even syringe failure.

Principle of Break Loose and Glide Force Testing
—— ISO 7886-1 Annex E

IL prova di forza di sgancio e di scivolamento process uses a mechanical testing machine to push the syringe plunger while measuring and recording the applied force. The test evaluates how smoothly the plunger operates under standardized conditions, such as temperature and displacement speed.

During the test:

  1. The syringe is filled with water maintained at (23 ± 5)°C.
  2. The syringe nozzle connects to a water reservoir at a controlled level.
  3. The testing machine moves the plunger at a constant rate of (100 ± 5) mm/min).
  4. The system records:
    • IL break loose force (Fs) – force required to start piston movement.
    • IL mean gliding force (F) – average force during steady plunger movement.
    • IL maximum force (Fmax) – peak force observed during movement.

These parameters are plotted as a force-displacement curve, providing clear visualization of syringe performance characteristics.
