In an Elmendorf tear test, the 20 mm incision length sets the starter cut, and the 43 mm tear length defines the tear path the pendulum measures. That means your test setup has to keep specimen preparation, notch placement, and clamp positioning consistent from sample to sample. On this tester, those dimensions are built into a controlled setup that supports repeatable tear resistance testing across textiles, nonwovens, paper, paperboard, and thin films.
The main setup impact is method discipline. If the specimen is not cut cleanly or seated the same way each time, tear results can shift because the tear does not start or propagate uniformly. This system uses automatic sample cutting and pneumatic clamping to help standardize that part of the workflow and reduce operator-driven variation in daily QC and R&D testing.
