标准摘要
[中文适用范围]： 本部分规定了当纸或纸板处于平衡状态的相对湿度从(33 2) %变化到(84 2) %时吸湿膨胀率的测定方法。 目的是涵盖在高湿度条件下使用的纸和纸板的应用。 它还可用于确定在某些印刷过程中纸张短期内可能受到的过度潮湿的影响。 该方法具有普遍适用性。 但不适用于crpe纸和瓦楞纤维板。 [外文原描述]： This part specifies a method for the determination of hygroexpansivity when the paper or board is subjected to a change in the relative humidity with which it is in equilibrium from (33 2) % to (84 2) %. The purpose is to cover applications of paper and board intended to be used in high humidity conditions. It may also be useful in determining the effect of excessive moisture to which paper may be subjected for short periods during some printing processes. The method is generally applicable. However, it is not suitable for cr pe papers and corrugated fibreboard.
英文名称Paper and board — Measurement of hygroexpansivity — Part 2: Hygroexpansivity up to a maximum relative humidity of 86 %
