This International Standard specifies the atmosphere for the conditioning and testing of samples and test pieces of tobacco and tobacco products. It is applicable to tests on tobacco, tobacco products, and materials used in the manufacture of tobacco products for which prior conditioning is necessary. It is not applicable in the case of test methods and test conditions stipulated in other International Standards (see bibliography). NOTE Atmospheres for conditioning and testing for other tobacco products (e.g. cigars, pipe tobacco or snuff tobacco) may differ from those specified in this International Standard. If required separate standards will be drafted.
