Interfiber Bond Testing Using the TAPPI-UM 403 Internal Bond Tester

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of TAPPI-UM 403 test. TAPPI UM 403 is a testing method developed by the Technical Association of the Pulp and Paper Industry (TAPPI) to measure the interfiber bond strength of paper or board using the Internal Bond Tester.

Interfiber bond strength is an important property of paper materials as it relates to the ability of paper to maintain its integrity under various conditions such as printing, converting and processing.

Internal Bond Tester is used for this test. It consists of two clamps, one fixed and the other movable, that holds the sample. A pendulum or other mechanism is used to apply force to the moving clamp, causing the sample to separate into layers.

TAPPI UM 403 provides a standardized method for evaluating interfiber bond strength required for a variety of applications in the paper and board industry. This testing helps manufacturers ensure their products meet quality standards and perform well in end-use applications such as printing, packaging and more.
