标准摘要
[中文适用范围]： 取消并取代第一版（1984 年）。 指定一种测量纸张和纸板平滑度的方法，称为 Bekk 方法。 特别推荐用于光滑的纸张和纸板。 然而，对于非常光滑的样品，测量时间可能会太长而不切实际。 不建议用于厚度大于 0.5 毫米的材料或渗透性很强的纸和纸板，因为通过测试件的空气量会影响结果。 不推荐用于新闻纸，也不适合粗糙纸和纸板。 [外文原描述]： 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.
