Bendtsen roughness
31.10.2011 - Cartonboard Know-How
Bendtsen roughness indicates the surface smoothness of coated cartonboard.
Unit | ml/min |
Test Standard | ISO 8791-2 |
General information
Especially for rougher surfaces, the Bendtsen measuring method is more suitable than the PPS measuring method. For determining the Bendtsen roughness, air is pressed within a certain time under defined conditions through a gap between the cartonboard and a metal ring, which is pressed onto the cartonboard. The result shows the air volume per minute (ml/min) which has leaked out. A lower value represents a smoother surface.
