This method is used to investigate the peel adhesion of self-adhesive tapes. This allows the user to understand the strength of the adhesive and indicates results such as peel adhesion and average loads applied. The EN 1939 test method is suitable for use with most self adhesive tapes and can indicate the performance of the tape in use.
The specimen consists of a rigid substrate to which the adhesive tape is stuck. A special roller is usually used so that the tape is applied with a constant force. The prepared specimen is then loaded into a tensile testing machine, and the tape peeled from the substrate in a
180° direction. The peel force is recorded and results such as the average peel force are determined. Because the force fluctuates rapidly during the test, it is critical that the data is recorded at the fastest possible rate. Higher specification tensile testers, such as the
5900 Series, feature data rates of 1kHz or greater, ensuring that the peel force is recorded as accurately as possible.
We recommend reviewing the standard in full to understand the test fixture and results requirements relevant to the materials and adhesives you are interested in prior to purchasing equipment.
