Puncture test fixture 2810-195

specimen

Burst or puncture fixtures are used to determine the resistance of a material to the penetration of a probe. The material is typically held by a set of clamping rings, and undergoes biaxial stresses representative of those encountered during actual use. PRINCIPLE OF OPERATION Fixtures are typically comprised of a lower frame with a clamping mechanism that attaches to the base of the testing system, while a probe attaches to the load cell on the moving crosshead. The probe is then moved onto the specimen at a low rate of travel until failure occurs. Common results from these tests are maximum force, force at break, penetration distance, and energy to break. APPLICATION RANGE •Type of test: Puncture •Specimen material: Woven and knitted textiles •Temperature Range: 10 to 40 °C (50 to 100 °F)
