  Introduction to the Needle Penetration Test Method The  needle penetration test  method is a reliable technique used to measure the mechanical properties of various materials. By inserting a needle or probe into a material, the method evaluates key characteristics like firmness, elasticity, or resistance. This testing method is vital across multiple industries: Pharmaceuticals: Ensures the quality and durability of tablets and capsules. Food Industry: Measures the texture of gels, creams, or solid products like fruit. Its accuracy and versatility make it a critical tool for quality assurance and material evaluation. How Does the Needle Penetration Test Work? The process involves a penetrability  Tester|、Plastics Testing factory  applying a controlled force to a needle, measuring its depth of penetration into the material. Key Components of the Test: Penetrability Tester: The primary equipment that controls the needle’s movement. Material Sample:...

 In the medical device industry, ensuring the safety and efficacy of needles is critical. One of the most effective methods for evaluating the integrity of medical needles and their components is Penetrability Testing. This test helps assess the force required for needles to penetrate materials such as rubber stoppers or protective films. The use of a Penetrability  Tester|、Plastics Testing factory  in this context is essential in meeting internationally recognized standards, including ISO 7864, ISO 8871-5, and USP 381. Understanding Penetrability Testing Penetrability Testing involves simulating the puncture of a needle through materials to measure the force required for penetration. This process ensures that medical devices, particularly hypodermic needles and rubber stoppers, meet rigorous safety and performance criteria. The test is typically performed using a Penetrability Tester, such as the NPT-01 Needle Puncture Tester, which is equipped with various sample holdin...
