Comparison with the Scott Bond Test
The internal bond test offers greatly reduced result dispersion compared to the Scott bond test, which is used to determine similar paper properties. Other similar tests include ply-bond strength according to DIN 54516 and the Scott bond test according to TAPPI T 569, both of which apply peel loading to the specimen. A pendulum impact tester is used for the Scott bond test. The test therefore takes into account the high processing speeds typical for this material, but is considerably less reproducible due to internal energy losses through friction and vibration.
