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
Preview
Summary
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.
NOTE For an estimate of the air permeability of materials outside the scope of this document, see Note 3 in 5.1.2 and 7.6.1.4.
