초록 ▼

A reference standard for calibrating ultrasonic flaw detection test equipment and the like. The standard comprises a substantially solid body having at least one surface adapted to be engaged by the test equipment and a void of known dimensions located within the body at a known distance from the test equipment engaging surface. The standard may be constructed of two or more substantially solid bodies, at least one of which contains an aperture of known dimensions, and at least one of which is of known length and contains a surface adapted to be engaged by the test equipment, the bodies being diffusion bonded together to substantially eliminate the bond line such that the aperture forms a void of known dimensions within the substantially solid body at a known distance from the equipment engaging surface. In one embodiment, test equipment may be dynamically calibrated by rotating the standard about its longitudinal axis to produce a dynamic calibrated signal. The void formed within the standard by the aperture may be filled with an inclusion representing material to realistically modify the ultrasonic reflectance and attenuation characteristics.

A reference standard for calibrating ultrasonic flaw detecting test equipment and the like comprising a substantially solid body having at least two spaced surfaces adapted to be engaged and abutted by the test equipment for introducing ultrasonic energy into said body from either surface, and at least one void of known dimensions totally enclosed within said body at a known distance from said surface, said void having two spaced substantially planar surfaces configured to reflect substantially all of the ultrasonic energy impinging on said planar surfaces toward the test equipment, the volume of said void being substantially less than the volume of said body. The method for calibrating ultrasonic flaw detection test equipment and the like by introducing ultrasonic sound waves of known characteristics from the test equipment into a continuously rotating reference standard containing a void and receiving and interpreting waves reflected from said void comprising the steps of: (a) rotatably supporting a substantially cylindrical reference standard having a void of known dimensions totally enclosed within the standard at a known distance from the surface of the standard, said void having two spaced substantially planar surfaces configured to reflect substantially all of the ultrasonic sound waves impinging on said planar surfaces toward the test equipment; (b) continuously rotating the standard about its longitudinal axis; (c) introducing ultrasonic sound waves of known characteristics from said test equipment into said standard; and (d) receiving and interpreting waves reflected from said void to calibrate the test equipment.
