| ISO 5627 | Paper and board - Determination of smoothness (Bekk method) |
Cancels and replaces the first edition (1984). Specifies a method of measuring the smoothness of paper and board, called the Bekk method. Especially recommended for smooth paper and boards. However for very smooth samples, measurement times may be impractically long. Not recommended for materials greater than 0,5 mm thick or very permeable papers and board, since the amount of air passing through the test piece can influence the result. Not recommended for newsprint and not suitable for rough papers and boards.
