Puncture resistance testing is a test method for measuring the strength of a sample, usually film, rubber, or paper, to withstand tearing by a probe when force is applied at a constant velocity. In most cases, a specially designed test apparatus is required to properly fix the sample for testing. Test probe design also varies from standard to standard. Advanced laboratories have a wide variety of equipment for accurate and repeatable puncture resistance testing, including puncture test apparatuses and probes.
Today, there are many standards developed by the American Society for Testing and Materials (ASTM) for determining puncture resistance. Here are a few of them:
In short, puncture resistance is a measure of the maximum force or energy required to penetrate a material. This type of biaxial stress is also seen in the packaging of films, for example when packaging hard protrusions such as pelleted dry foods and frozen vegetables. The test method defined in the ASTM 1306 standard is a method for determining the strength, energy, and elongation to perforation of flexible barrier films and laminates. In the puncture test of textiles, a ball bearing or rod is generally used as a puncture probe.
Our organization also provides puncture resistance testing services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
