Materials used as cigarette papers, filter plug wrap and filter joining paper, including materials having a discrete or oriented permeable zone and materials with bands of differing permeability. Determination of air permeability Ingestion-build-52208 Requirements for other types of1 Scope 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(min1cm2) at 1 kPa. In addition, it is applicable to banded cigarette papers, with bands of a width of at least 4 mm. NOTE For an
