Abstract: To verify the accuracy of correction formula for the measurements of air permeability standards in ISO 2965-2009,18 air permeability standards were tested in an atmospheric pressure chamber at 22,24℃ and 86,93,99,101,106 kPa,respectively.The results showed that:1) The measurement values of linear standards could be used directly without correction.2) The measurement values of non-linear standards should be corrected to the standard conditions.The mentioned results were verified by the experiments of the effects of linear standards and non-linear standards on the measurements of air permeability of cigarette paper before and after correction.
