A method for testing integrity of a plugged honeycomb structure includes forming a condenser at a first end of the honeycomb structure, passing a vaporous stream into a second end of the honeycomb structure, wherein a column of the vaporous stream emerges at the first end of the honeycomb structure from cells in the honeycomb structure that are defective, and observing the first end of the honeycomb structure for condensation spots formed by contact between the column of the vaporous stream emerging at the first end of the honeycomb structure and the condenser. An apparatus for accomplishing the method is also disclosed.
