Introduction to the Needle Penetration Test<\/strong><\/h3>\n\n\n\n

\u0625\u0646 Needle Penetration Test<\/strong> is a critical process in assessing the resistance and reliability of materials such as injection needles, vial stoppers, and other medical components. By evaluating the force required for a needle to penetrate a given material, this test ensures compliance with standards like \u0623\u064a\u0632\u0648 7864<\/strong>, ISO 8871-5 ISO 8871-5<\/strong>, \u0648 USP 381<\/strong>, safeguarding product integrity and user safety.<\/p>\n\n\n\n

Vial stoppers serve as critical seals for pharmaceutical containers, requiring adequate puncture resistance to maintain sterility without excessive force. The Needle Penetration Test<\/strong> evaluates stopper materials to ensure optimal performance under ISO 8871-5 ISO 8871-5<\/strong> \u0648 USP 381<\/strong> \u0627\u0644\u0645\u0639\u0627\u064a\u064a\u0631.<\/p>\n\n\n\n

Testing Process and Principles<\/strong><\/h3>\n\n\n\n

The test procedure typically involves a needle mounted to a load cell and a stationary sample holder. The needle moves at a controlled speed to puncture the material while recording the force exerted. This data helps manufacturers understand the material’s resistance, guiding product design and quality control.<\/p>\n\n\n\n
