Understanding the stroke range analysis diagram of tensile tester

GB13022-91The description of the fixture in the "Tenabled Performance Test Method of Plastic Films" is:Tension testerAppropriate fixtures should be provided, which should not cause the sample to break at the fixture. When any load is applied, the fixtures on the test machine should be able to be immediately aligned into a line so that the long axis of the sample coincides with the tensile direction through the centerline of the fixture. ... Place the sample in the two fixtures of the test machine, so that the longitudinal axis of the sample coincides with the center of the upper and lower fixtures, and should be appropriately tight and tight to prevent the sample from slipping and breaking in the fixture.Tension testerThe fixture should be lined with elastic materials such as rubber. "Due to the special mechanical properties of polymer materials and the special use of flexible packaging materials, the test specimen tested by the soft packaging material is very thin, and general fixtures cannot meet the requirements. Improper use will cause the sample to break at the fixture and cause the test to fail.

The itinerary is on500mmThe following equipment accounts for13.9%; itinerary in500~900mmequipment,56.9%; itinerary in901~1100mmequipment,20.8%; itinerary in1100mmThe above equipment only accounts for8.4%. However, in the electronic tensioning machine counted this time, not all the equipment with large strokes are used for testing flexible packaging materials, but are partly used for tensile tests of artificial wood boards, canvas, curtains, copper and other materials.
