ISO 1974 is the international method for the out-of-plane tearing resistance of paper using the Elmendorf pendulum. To match this to your program, talk with our team.
What ISO 1974 Covers
It measures the force to propagate a tear through paper with a pendulum, the ISO Elmendorf tear method.
How the Test Is Run
Pre-cut specimens are torn by a falling pendulum, and the energy lost gives the tearing resistance.
Why It Matters
Tear resistance indicates paper toughness and fiber quality; a calibrated Elmendorf tester and controlled conditioning are used.
Reading the Designation
Cited as ISO 1974 with its edition year. Confirm the edition and specimen or fixture requirements before finalizing setup. To configure a testing setup, request a quote.
Related Standards
TAPPI T 414 and DIN 53128 are equivalent paper Elmendorf methods.
