ISO 9073-4 is the test method for the tear resistance of nonwoven materials using the trapezoidal method. To match this to your program, talk with our team.
What ISO 9073-4 Covers
It measures the tear force of nonwovens with a trapezoidal specimen pulled in a tensile machine, suited to the random structure of nonwovens.
How the Test Is Run
A trapezoid marked on the nonwoven is gripped along its non-parallel sides and pulled at a controlled rate, and the tear force is recorded.
Why It Matters
Tear resistance governs nonwoven durability; grips and a tensile frame with a suitable force trace are used.
