The Internal  Bond  Tester utilizes  the  Scott method to produce a high speed Z-direction rupture of  paper  and  paperboard. It is a dynamic test that measures and defines strength in terms of energy absorption.

Ideal for monitoring the effects of dry strength additives and to evaluate stock preparation and refining. In addition to correlations with customer complaints, in-mill  processing trouble-spots are of growing  interest.  Examples  of dry-end analysis are monitoring Z-direction strength deterioration due to calendaring or the application of  relatively  brittle  coatings. The increasing use of recycled fiber and dry strength additives in both paper and board open even more applications and create economic value for the test today. At the product research and development level, sequential photographs of the ruptures can further enhance analysis and understanding.
