<p>Means and method for determining the tensile strength of ceramic material. The means comprises a pressure chamber (1), two cylindrical bodies (13, 14) axially displaceable therein, and having bore holes (24, 25) for insertion and securing, by means of adhesion, of a test rod (12) having substantially the same diameter along its entire length. Sealing means (6a, 6b) are provided between the pressure chamber wall and said cylindrical bodies (13, 14). A source of pressure medium (20) and a pressure meter (23) communicate with a space between the bodies (13, 14) in the pressure chamber (1). The method according to the invention comprises combining two cylindrical bodies (13, 14) and a test rod (12) to form a unit with the aid of an adhesive, inserting this unit into a pressure chamber (1) and sealing the gap between the bodies (13, 14) and the pressure chamber wall with seals (6a, 6b), pressurizing the space defined between the pressure chamber wall and said bodies (13, 14), measuring the pressure in said space, and recording the pressure at which the test rod (12) fractures.</p> |
