Internal tearing resistance of paper (Elmendorf-type method)
2021
7
offline
This method measures the force perpendicular to the plane of the paper required to tear multiple plies
through a specified distance after the tear has been started using an Elmendorf-type tearing tester. It does not measure
edge-tear resistance. The measured results may be used to calculate the approximate tearing resistance of a single
sheet. It is not suitable for single-ply tear testing. ....
