The mean force required to continue the tearing of an initial cut in a single sheet of paper is expressed as the internal tearing resistance. If the initial slit is made in the machine direction, the result is given as machine direction tearing resistance and similarly for the cross-machine direction (ISO 1974). Why measure tearing resistance?ISO 6383-1:2015(E) 8 Number of test specimens 8.1 A minimum of five test specimens shall be tested in each of the required directions of testing. 8.2 Specimens which show a tear out of line to the extent that the tear reaches one of the edges of the test specimen shall be discarded and further specimens tested (see 11.3). 9 Speed of testing
One way to measure tear resistance is through the Pendulum Method or Elmendorf Tear Test, as defined by ASTM D1922. The Elmendorf Tear Test is a simple and reliable way to measure the force required to propagate a slit in a plastic film a fixed distance to the edge of the test sample. The test is performed using a pendulum impact tester, which . Tear resistance testing can be found in plastic film, paper and textile industries. Tear resistance is the measurement of a sample’s ability to resist tearing. Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for the purpose of acceptance testing is .
