Methods of testing a honeycomb filter include the step of maintaining an average temperature of the honeycomb filter and/or fog within a range of from about 10&#xb0; C. to about 30&#xb0; C. and flowing a fog with moisture droplets into the honeycomb network of channels at the first end portion of the honeycomb filter, the fog including a relative humidity of at least 80%. In further examples, the moisture droplets include a mean droplet size of from about 1 micron to about 25 microns.

Methods for testing a honeycomb filter

Methods of testing a honeycomb filter for defects include the step of wetting at least one of the first end portion and the second end portion to provide at least one wetted end portion. The method further includes the step of monitoring the second end portion for fog passing through the filter.
