ASTM D3330/D3330M-04 Test for Peel Adhesion of Pressure-Sensitive Tape

ASTM D3330-04 is used to determine the peel adhesion of pressure-sensitive tape. Peel adhesion is the force required to remove a pressure-sensitive adhesive from a testing plate or its own backing material. Values stated in either SI or imperial units are to be regarded separately as standard.

Frequently Asked Questions

This test method is widely used in Quality assurance/Control, research, & development for industries that apply Pressure Sensitive Tapes, viz., packaging, electronics, automotive, etc.

ASTM D 3330: Specifies imperial units, is the usage customary in the United States. ASTM D3330M-04: Since this test method is in metric units, it can be used globally or in industries observing the metric system.

Most samples of the tapes are 1 inch in width, but it can also be wider based on the type of tape being used. The sample is applied to the test surface in a standardized manner, applying the same pressure and the same environmental conditions. The sample is applied uniformly so the results are consistent.

The present technique involves peeling the tape at a steady pace. Usually, 180 degrees and the speed is set to 300mm/min (12 inches/min). Other angles and speeds might be applied depending on the test's specific characteristics.

The roller should have a total weight of 2 kg (4.5 pounds) and a width of approximately 45 mm (1.75 inches).
