Needle penetration test
Discover the essentials of the needle penetration test, including testing principles, apparatus setup, and procedure guidance.
Needle penetration has been used for decades to determine the stiffness of bituminous binders at intermediate temperature. For unmodified bitumens, the penetration test correlates well with the stiffness of the bitumen measured, using the DSR, at the same temperature (25 °C) and at a frequency of 0.4 Hz.
Needle penetrability test evaluates the ease with which a sharp object, typically a needle or stylus, can penetrate a sample. The force required for penetration is measured, providing data that can help manufacturers determine the material's texture, hardness, and suitability for specific applications. This test method is especially vital in industries like pharmaceuticals, where the ...

To overcome these difficulties, a new and portable light-weight testing device, Needle Penetrometer (NP), has been developed in Japan. But there is no any standard or suggested method available for this test. It is a non-destructive test applicable both in the field and laboratory with minimum sample preparation.
To measure the syringe needle penetration force, the resistance force is measured when the needle is pierced into an object. Various studies have been conducted on syringe needles to reduce pain of injection, which have led to improving the shape of the tip, the thickness of the needle, processing, and tip finishing method.
