D3330 (Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape)

D3330 is a standardized test used to measure how well a pressure-sensitive tape sticks to surfaces. In this test, a strip of tape is applied to a smooth surface under controlled conditions, then cut and pulled back at a consistent angle and speed. The force required to peel the tape off is measured, providing an adhesion value. This helps manufacturers and users evaluate the tape’s sticking power, ensuring it performs reliably in real-world applications. Essentially, D3330 provides a consistent way to compare how sticky different tapes are, which is important for selecting the right adhesive for specific uses.
