Sample bottle plug needle permeability residual sealing force and torque test
Test standard: comply with ISO 8362-7, United States Pharmacopoeia 1207.3, etc
The final strength test associated with the vial involves characterizing the force required for the hypodermic needle to pass through the elastic seal. The penetration test in USP 381 and the description of the glue plug should allow the needle to pass for 10N so that the drug can be easily applied, and the needle is not damaged or blunted through excessive force.
