PAUT IIW Calibration Block (ISO 19675 Phased Array Block)

The process starts with high-quality, fine-grained steel, produced in a special size by our preferred mill. Material selection is followed by heat treatment, flaw detection, material attenuation check, material velocity checks (longitudinal and transverse wave,) machining and surface finish preparation, block identification, in-house nickel-plating, and preparation of a comprehensive documentation package.
Each block will ship with a documentation package including:

• Certification Report stating conformance to ISO 19675
• Material Test Report for traceability of the specific heat of raw material used
• PMI Test Report showing results of chemical analysis via XRF testing
• Dimensional Report with main physical dimensions of the block and hole diameters as-measured.
• Material attenuation results in accordance with para. 5.2.3 of the spec
• Velocity measurements in accordance with Annex A of the spec

The PAUT IIW Block, made in accordance with ISO 19675 was designed by an international committee of NDT experts with the express purpose of creating a globally accepted, standardized block for Phased Array Ultrasonic calibrations. Before the development of this spec, there were no international standards describing a specific block for calibrating PAUT systems.

• Dimensions: 25mm wide x 100mm tall x 300mm long, with 100mm and 50mm radii
• Material: 1018 Steel, Nickel-plated
