The constant radius sample template (60-3004) is ideal for plastic films. The sample template is designed to meet ASTM D1922 for propagation tear resistance with a sample width of 63 mm.
The template is placed on the sample with the plate facing down as shown below. A straight blade is used to cut along the edge of the template.
Cut Width: 63 mm (2.48 in)
Cut Length: 76 mm (3 in)
Note that this template does not cut the pretest slit, that can be cut with the ProTear Elmendorf Tear Tester prior to testing.
ASTM D1922 is the standard test method for evaluating Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method
