GB/T 461.1-2002 "Paper and board—Determination of capillary rise—Klemm method" specifies the Klemm method for determining the capillary rise of paper and board, which is applicable to various types of paper and board. The test involves immersing one end of the specimen in a liquid, allowing the liquid to rise along the specimen through capillary action, and recording the height of liquid absorption within a specified time. The standard specifies requirements for liquid selection, specimen dimensions, and testing environment to reflect the capillary water absorption properties of paper.
