This International Standard specifies a method for determining the (out-of-plane) tearing resistance of paper. It can also be used for boards having a low grammage if the tearing .This Complete Guide of the Elmendorf Tear Testing explores tear resistance testing dimensions, application areas, standards, methodologies, troubleshooting, and the future landscape of tear analysis. Key takeaways and practical insights empower informed decisions in material science. Application of Elmendorf Tear Testing in Industry1.1 This test method covers the determination of the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started, using an Elmendorf-type tearing tester. Two specimens are cited, a rectangular type, and one with a constant radius testing length.
