GB/T 22363-2008 "Paper and board—Determination of roughness (air-leak methods)—Bendtsen method and printing surface method" specifies two methods for determining roughness based on the air-leak principle, applicable to various types of paper and board. The Bendtsen method assesses roughness by measuring the amount of air leaking through the gap between the test specimen and the test ring. The printing surface method simulates printing pressure conditions during testing. The standard clarifies the instrument structure, operational procedures, and result calculation methods, providing diverse options for detecting the surface roughness of paper.
