本文件规定了测定空气渗透性（AP）的方法。 适用于卷烟纸、滤嘴包装纸、滤嘴连接纸等材料，包括 具有定向渗透区或离散渗透区的材料，其中 在1 kPa条件下，渗透率超过10 cm3·（min-1·cm-2）。此外，它还适用于宽度至少为4mm的带状卷烟纸。交叉引用:ISO 3402ISO 187ISO 5725:1986购买本文件时可获得的所有现行修改件均包含在购买本文件中。

This document specifies a method for the determination of air permeability (AP). It is applicable to materials used as cigarette papers, filter plug wrap and filter joining paper, including materials having an oriented permeable zone or discrete permeable zones where the measured permeability is in excess of 10 cm3·(min-1·cm-2) at 1 kPa. In addition, it is applicable to banded cigarette papers, with bands of a width of at least 4 mm.Cross References:ISO 3402ISO 187ISO 5725:1986All current amendments available at time of purchase are included with the purchase of this document.
