The Puncture Resistance Tester works by applying a force to a pointed probe or needle and pressing it against the material being tested. The force required to puncture the material is measured and recorded, and the results are given in terms of the maximum force required to puncture the material or the resistance to puncture in newtons or pounds. It typically consists of a sample holder, a pointed probe or needle, and a mechanism to apply a force to the probe and measure the force required to puncture the material. It is based on standard ASTM D781. The puncture resistance tester is used in a variety of industries, such as packaging, construction, and manufacturing, where it is important to understand the puncture resistance of materials. It is also used in product design, to ensure that the product has the desired puncture resistance properties and is suitable for its intended use.
