In the pharmaceutical and medical device industries, ensuring the integrity of syringe components is critical. One essential quality check is the this test. This evaluation measures the strength of the connection between the Luer lock adaptor (LLA) collar and the syringe barrel, preventing component separation during use.
If the pull-off force of the Luer lock adaptor collar is too low, the collar may detach from the syringe during handling or injection, leading to medication leakage, incomplete dosing, or even serious patient injury. On the other hand, if the force is too high, assembly processes may become difficult, increasing the risk of damage during manufacturing.
Therefore, conducting standardized this testing is critical to ensure the secure attachment of the collar, maintain the functional reliability of the syringe, and protect patient safety.
Syringetest.com offers precise, reliable testing equipment for Luer lock adaptor collar pull-off force assessments, helping ensure your syringes meet global quality standards with confidence.
The ISO 11040-4 standard, particularly ISO 11040-4 Annex G3, outlines the procedure for the Luer lock adaptor collar pull-off force test. According to these standards, the pull-off force test verifies the collar system’s ability to withstand axial forces, ensuring that syringes remain intact during critical operations such as medication administration. The method emphasizes consistent test speeds, appropriate load cell selection, and high-frequency sampling to ensure accurate, reliable data.
Following ISO 11040-4 Annex G3 improves test consistency across laboratories and manufacturers, fostering trust in product quality and regulatory compliance.
The core idea behind this test is simple: it measures the maximum axial force required to detach the LLA collar from the syringe barrel. A strong pull-off force means the LLA collar is securely attached, minimizing the risk of disconnection during use.
The key principle focuses on:
Accurate testing of Luer lock adaptor collar pull-off force demands precision equipment:
Materials:
Important:
The sampling rate must be no less than 100 Hz for general tests, and 500 Hz for peak measurements, ensuring fine data resolution and accuracy.
Performing this test correctly ensures accurate, repeatable results:
Use syringes that have undergone the full sterilization and preparation process.
Stop the test when the LLA collar clearly separates from the syringe.
The maximum force peak on the curve represents the pull-off force.
Performing the Luer lock adaptor collar pull-off force test according to ISO 11040-4 Annex G3 is vital for ensuring the mechanical security of Luer lock syringes. Proper execution and documentation provide assurance that the syringes can endure the stresses of clinical use without failure.
