Needle Penetration Testing According to ISO 7864 for Hypodermic Needles ISO 7864 is an international standard for sterile hypodermic needles for single use that specifies the requirements and test methods for assessing the mechanical properties of these needles. The standard covers the needle penetration test method, which is used to measure how much force is required to insert a needle into a specific substrate. This test method is crucial for evaluating the functionality and performance of hypodermic needles, ensuring their suitability for medical use. The Needle Penetration Test Method is essential for testing the drag force and penetration force of hypodermic needles. Both forces are critical in determining the ease
