Abstract:

An apparatus and method to strength test porous ceramic honeycomb bodies. The apparatus includes an interlayer between at least one platen and a surface of the high porosity honeycomb body to be tested. The method includes disposing at least one interlayer between at least one platen and an end face of the body, applying a force to the high porosity ceramic honeycomb body and monitoring a result of applying the force. The interlayer comprises a surface weight of about 350 g/m.sup.2 and a thickness in a direction N between facing surfaces load platens of at least about 20 mm. Axial and radial localized stamping tests also strength test porous ceramic honeycomb bodies.
