Paper - Edge Tear Resistance

When paper is subjected to high stresses on handling equipment, good edge tearing resistance is very important. In determining the edge tear resistance of a paper sample, a strip of paper is simultaneously torn at opposite edges of the strip by means of a thin, V-notch beam held in a stirrup fastened to a Chatillon^® tensile system. A tearing force is applied at a constant rate of elongation until the paper begins to tear. This test is limited to papers which will fold evenly over the V-notch beam.

Industry standards for determining the edge tear resistance of paper is:
- TAPPI T-470
