PAUT-Phased Array Standard Calibration Blocks (Inch Version) Special Alloy Phased Array Calibration Standard Blocks are used for angle beam verification, probe angle exit points, calibration for wedge delay, sensitivity and DAC/TCG for thicknesses up to 50mm. The reference block shall be used which allows a minimum of a 3 point TCG establishment throughout the range specified in the scan plan for all configured angles . The block shall be made of sufficient thickness and length to allow calibration of reflectors throughout the entire examination volume to be tested. Each reference block shall have at least three side drilled holes at a range of depths to cover the entire material range to be tested. Each hole shall be detected by the PAUT system as configured per the scan plan and sensitivities shall be adjusted as necessary to provide sensitivity equal to or greater than SSL. Geometry: The three radii (0.5”, 1” and 2”) allow for exit point verification, velocity and sound path calculations. This metric block contains five holes at 0.05” diameter drilled through the 1” width, located at 0.1”, 0.2”, 0.4”, 0.6”, 0.8”, 1.2”, 1.4”, 1.6”, 1.8” and 1.9” from the respective scanning surface. Dimensions: 18” (L) x 2” (W) x 1” (T) Material: Special Alloy
