HVL CS Structural Standard DWG.pdf

The document is a technical drawing for a PAUT (Phased Array Ultrasonic Testing) Calibration Standard with precise dimensional specifications. The standard is made from HY-80 material (MIL-DTL-16216 Plate), sized at 15.50" x 3.25" x 1.25", and includes specific design requirements such as:

Key technical details include engraving the alloy with a unique serial number on one side, defining hole depths from the top scanning surface, and specifying scanning surfaces with 125 Ra roughness. The drawing provides detailed dimensional tolerances for multiple sections, including hole locations, depths, and diameters. Additional notes specify requirements for measurement, surface finish, and material preparation, such as electroplating ferrous steel standards with nickel for corrosion resistance and requiring a dimensionally qualified mechanic to take measurements and record results.
