PAPER AND BOARDS – DETERMINATION OF ROUGHNESS/SMOOTHNESS (AIR LEAK METHODS) – PART 2 : BENDTSEN METHOD (ISO 8791-2 : 1990, IDT)
This part of MS IS0 8791 specifies a method for the determination of the roughness of paper and board using the Bendtsen apparatus. It should be read in conjunction with IS0 8791-1.
The method is applicable to paper and board which have Bendtsen roughness values between about
50 ml/min and 1 200 ml/min. It is not suitable for soft papers which allow the land to make a significant
impression on the surface or for high air permeance papers which allow a significant flow of air to pass
through the sheet, or for papers which will not lie flat under the heavy metal annulus.
