NM01SC001

The Curtis Industries TYPE SC CALIBRATION BLOCK is a meticulously manufactured reference standard essential for the accurate calibration and performance verification of ultrasonic testing (UT) equipment. Constructed from high-quality 1018 carbon steel, this calibration block provides a reliable medium with consistent acoustic properties, crucial for ensuring the precision of ultrasonic inspections.

The specific designation "TYPE SC" by Curtis Industries indicates a particular configuration of this calibration block, designed to meet specific calibration requirements. While the exact features may vary based on Curtis Industries' specific design, Type SC blocks typically incorporate precisely machined geometric features that serve as known reflectors for ultrasonic waves. These features often include:

• Specific Overall Dimensions: Accurate length, width, and thickness to provide reference points for thickness measurements and distance calibration.

• Side-Drilled Holes (SDHs): One or more precisely sized and located side-drilled holes, acting as artificial subsurface reflectors for sensitivity calibration, time base adjustment, and beam profiling of ultrasonic transducers.

• Notches: Surface or edge notches of defined dimensions (e.g., rectangular, V-notch) used to simulate surface-breaking or near-surface flaws, aiding in the calibration of flaw detection sensitivity and sizing techniques, particularly for angle beam inspections.

• Engraved Identification: Clear and permanent markings identifying the block type, material, and potentially serial numbers for traceability.

The use of 1018 carbon steel ensures a consistent and predictable ultrasonic velocity, a fundamental requirement for accurate calibration. Curtis Industries, a reputable manufacturer of NDT reference standards, guarantees the dimensional accuracy and material composition of this Type SC calibration block. Often, these blocks are supplied with a certificate of conformance or dimensional report, providing documented evidence of their precision.
