Puncture testing primarily involves tear and stiffness and measures the resistance of a test specimen to puncture. ADMET offers a selection of puncture fixtures with varying probe and clamp sizes designed according to many ASTM and ISO test standards. Common puncture testing definitions and keywords include:
Puncture strength testing. Puncture strength tests are used to determine the puncture or rupture characteristics of a material. This is generally a compressive test where a material is compressed by a probe or other type of device until the material ruptures or until an elongation limit is achieved.
4 de may. de 2024 · A lumbar puncture (spinal tap) is a test used to diagnose certain health conditions. It's performed in your lower back, in the lumbar region. During a lumbar puncture, a needle is inserted into the space between two lumbar bones (vertebrae) to remove a sample of cerebrospinal fluid.
Puncture Resistance Testing ou puncture testing is a process used to assess the ability of a material to withstand penetration or puncture by a sharp or pointed object. It provides vital information about the puncture strength, energy absorption, and failure characteristics of the material being tested.
In a penetration or puncture test a probe is made to penetrate into the test sample and the force necessary to achieve a certain penetration depth or the depth of penetration in a specified time, under defined conditions, is measured and used as an index of e.g. hardness, firmness, toughness.
Understanding puncture resistance is necessary if films are used as packaging material for food or parts with sharp edges. The static puncture test to EN 14477 measures this behavior using a pointed tip with a diameter of 0.8 mm. This test is also known as the Parker Ball-Point Test.
Puncture testing, performed to determine the penetration or the puncture strength of materials used in packaging, food, textiles, and medical industries, measures properties such as maximum force, breaking strength, and the penetration distance.
