Recommendation of Measurement Area for Air Permeability Determination of Super-Slim Cigarette Papers
PTM Technical Report
This report was prepared for submission to ISO in the context of a future revision of ISO 2965:2009 “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”. Specifically, neither the ISO Standard nor the equivalent CORESTA method (CRM 40) incorporate a recommendation for the measurement of samples of cigarette paper that are not fully enclosed by the smallest measurement clamp that is currently specified.
CRM 40 - Determination of Air Permeability of Materials used as Cigarette Papers, Filter Plug Wrap and Filter Joining Paper including Materials having an Oriented Permeable Zone (October 1994)
CRM 18 - Materials Used as Cigarette Tipping Papers Having a Perforated Zone - Determination of Unit Air-flow and Permeability (January 1991)
Report - 1st Collaborative Study on Air Permeability in Accordance with ISO 2965:2019 (November 2019)
Report - Recommendation of Measurement Area for Air Permeability of Super Slim Cigarette Papers (May 2012)
