Tear Tester  TT

This method measures the force perpendicular to the plane of the paper required to tear multiple sheets of paper through a specified distance after the tear has been started using an Elmendorf type tearing tester. the measured results can be used to calculate the approximate tearing resistance of a single sheet.

Significance:

Why this test? When paper is subjected to high stresses in converting machine operation and handling equipment, good tearing resistance is very important. Also to achieve a higher puncture resistance result of the board, a higher tearing of the paper is desired.
