A number of standard ASTM tests can be conducted on bag filters either to verify the bag filter's
conformity with purchase specifications or to use as a troubleshooting tool for problem
bag failures. As with all measurement techniques, the results of these bag tests are relative.
Often for these tests to be useful, they must be conducted over time in order to compare relative
degradation. In addition, with some of the newer fabrics, some of these tests may not be
meaningful. These tests can be used to indicate bag strength and flow loss. Four of the standard
tests performed are: permeability, MIT flex, Mullen burst strength, and tensile strength
(McKenna and Turner 1989). These tests can be conducted if the installed baghouse is having
problems with bag life or unusually high pressure drop.
