TAPPI T549

Test Materials: TAPPI T549 specifies the test materials as various types of paper, including packaging and specialty papers. Samples should be conditioned at standard temperature and humidity to ensure consistent results.

Test Process: The test process involves cutting paper samples into specified dimensions and using a pendulum-type tear tester. The samples are clamped, and a predetermined force is applied to initiate a tear, measuring the energy required for tearing.

Test Result Interpretation: Results are interpreted based on the energy required to tear the paper, expressed in grams per meter (g/m). Higher values indicate greater tear strength, which is critical for assessing the performance and durability of paper products in various applications.
