Roughness and Smoothness | Paper Testing | Smithers
Applicable test methods are BS 4420, ISO 8791/2, DIN 53108 and SCAN P21. Smithers are UKAS, ISO 17025 accredited to BS 4420. Bekk smoothness is again measured by the air leak method but, unlike the Bendtsen method, air is drawn across the surface of the test piece under a partial vacuum. Applicable standards are ISO 5627, Tappi T479 and DIN 53107.
