The Physical Test Methods (PTM) Sub-Group of CORESTA developed a Recommended Method (CRM N° 90) on the Determination of Dry and Wet Sealing Strength of Pouches for Smokeless Tobacco and Derivative Products. This collaborative study was carried out in order to determine repeatability and reproducibility statistics of the newly developed method.  The results show that laboratories are in general able to reliably perform the measurement of sealing strength as described in the CRM.
