IDENTIFICATION OF AN ALTERNATE SUBSTRATE FOR TESTING REDUCED IGNITION PROPENSITY CIGARETTES

摘要

Results from ASTM E2187, ISO 12863 and NZS/AS4830 for testing the ignition propensity of cigarettes have limitations that include sensitivity to mass, moisture content, and surface roughness of the filter paper substrate, variations in test results when using filter paper produced in a different location, and reliance on a proprietary product. Therefore identification of an essentially equivalent substrate with good reproducibility across various manufacturers and batches is underway. A summary of results of the initial screening and preliminary identification of a likely alternate substrate are presented.
