Bekk Smoothness Tester This air leak smoothness test is useful for very smooth surfaces, for example, coated label papers, coated free sheet, or other very smooth papers.

Likewise Bekk results have shown good agreement with subjective evaluations of low angle- illuminated surface photomicrographs.
