3 terms and units of measurement
3.1 terminology
Tearing force
Under the specified conditions, the average force required to continue tearing the specimen along the pre-cut, that is, the power consumed by tearing the specimen,
The ratio of the tear length of the specimen. The unit is Newton (N).
3.1.2 Tearing degree tearingtesistance
Tearing the average force required for each pre-cut specimen, that is, tearing the tear strength of the pre-cut specimen and tearing it at the same time
Number of sample layers. The unit is Newton (N).
3.1.3 tear length lengthoftear
Specified conditions in the specimen side of the incision, the incision terminal to the other side of the distance. The unit is in millimeters (mm).
3.1.4 pendulum capacity tearcapacityofpendulum
The rated tearing force corresponding to each pendulum, that is, the maximum tearing force given by the manufacturer. The unit is Newton (N).
3.1.5 Tear initial angle initialangleoftear
In the initial position, the fixture clamps the seam along the center line of the pendulum axis and the plane between the plane of the center line of the pendulum axis
Angle. The unit is degrees (°).
