Only cigarettes that pass the ASTM E2187-02B ignition strength test more than 75% of the time are allowed for sale in New York and Canada. We sampled a number of cigarette brands from these markets as well as from locations that were not designed to meet the ignition strength requirements. These cigarettes were then tested for ignition strength and analyzed to determine what changes, if any, were necessary to achieve the lower ignition strength. This study was not meant to be an exhaustive analysis of all cigarettes sold in these markets, but rather cigarettes were chosen to represent a broad range of design options. All cigarettes purchased in New York State and Canada met the ASTM ignition strength standard, but there were differences in cigarette free-air smoldering and deliveries.
