NM01IIW2.IAH36

The PH Tool Special Alloy IIW-Type 2 Test Block (Inch) made from AH-36 (ASTM A131) Structural Steel is a calibration standard used in ultrasonic testing (UT) for both angle beam and normal incident inspections. It is a modified inch version of the original IIW-Type 1 design, manufactured to comply with IIW, ASTM E164, and USAF T.O. 33B-1-1 specifications. This specific version is noted as "Bare," indicating it likely does not have any protective plating or coating.

Key Features:

• Material:AH-36 (ASTM A131) Structural Steel. This is a specific grade of structural steel commonly used in shipbuilding and offshore structures, providing defined acoustic properties suitable for calibration, and is relevant for inspections on similar materials.

• Inch Dimensions: Designed with inch measurements.

• Distance Calibration: Includes a 2.0 inch radius x 0.250 inch deep cut-out superposed on a 4.0 inch radius for distance calibration.

• Sensitivity Testing: Features #3 (3/64"), #5 (5/64"), and #8 (8/64") through holes for sensitivity testing or surface wave inspection.

• Distance Marks: Contains distance calibration marks to the 2.0 inch radius hole.

• Compliance: Manufactured in accordance with International Institute of Welding (IIW), ASTM E164, and U.S. Air Force NDI Manual T.O. 33B-1-1 specifications.

• "Bare" Finish: Indicates the steel is likely unplated or uncoated.

• PH Tool Quality: A trusted calibration standard from a reputable manufacturer in the NDT industry.

Applications:

• Calibration of ultrasonic flaw detectors for angle beam and normal beam inspections, particularly when inspecting AH-36 steel or similar structural steels.

• Setting metal distance and sensitivity settings.

• Determining the sound exit point and refracted angle of angle beam transducers.

• Evaluating depth resolution of normal beam inspection setups.

• Sensitivity testing using the through holes.

• Surface wave inspection.
