7th Proficiency Test (2014) for Physical Parameters of Cigarettes and Filters
PTM Technical Report
The CORESTA Physical Test Methods (PTM) Sub-Group proficiency test on physical parameters measures weight, diameter, pressure drop and filter ventilation of filters and cigarettes. The proficiency test serves as an assessment of the capability of the participating laboratories to properly measure physical parameters on cigarettes and filters. Although it is not required for a proficiency test to define the measurement method, in practice all laboratories closely followed CORESTA Recommended Methods or the respective ISO standards. The test results allow each laboratory to evaluate its performance in comparison to other laboratories and to derive actions for improvement.
This report covers the results of the seventh proficiency test on physical parameters conducted in 2014.
