PH TOOL IIW-Type 1 Calibration Block (Inch) - 304 Stainless Steel with Fitted Case

Achieve the highest level of accuracy and compliance in your ultrasonic testing with this essential PH TOOL IIW-Type 1 Calibration Block. Expertly machined from premium Type 304 Stainless Steel and supplied with a robust, custom-fitted case, this block is the industry-standard reference for calibrating flaw detectors and characterizing ultrasonic transducers.

Key Features & Benefits:

• Universal Calibration Standard: The IIW-Type 1 block is recognized globally and is used for a wide range of critical calibration tasks, including:

  • Calibrating Shear Wave Transducers: Accurately determine transducer index point (exit point) and refracted angle for angle beam inspections.

  • Calibrating Longitudinal Transducers: Set sound velocity and linearity for thickness measurements and normal beam flaw detection.

  • Resolution and Sensitivity Checking: Evaluate the ability of your system to detect and differentiate between flaws.

  • Distance Calibration: Verify distance accuracy for both compression and shear wave paths.

• Precision Design & Features: This inch-version block includes:

  • A large 4.0" (100mm) radius for distance calibration and beam path plotting.

  • A 1.0" radius with a 0.060" (1.5mm) deep cut-out.

  • Precisely drilled 0.060" (1.5mm) and 2.0" (50mm) diameter through holes for sensitivity and resolution checks.

  • Engraved reference marks (e.g., from 35° to 75°) to facilitate angle beam verification.

• Premium 304 Stainless Steel Construction: Manufactured from high-quality Type 304 Stainless Steel, offering superior corrosion resistance compared to carbon steel blocks, especially in humid or harsh environments. This ensures the block's long-term integrity and stable acoustic properties.

• Conforms to Industry Standards: Manufactured in strict accordance with:

  • International Institute of Welding (IIW) specifications.

  • ASTM E164 (Standard Practice for Contact Ultrasonic Testing of Weldments).

  • Often also referenced against BS 2704 Block A2 Mod. 1 and ISO 2400.

• Includes Fitted Wooden Storage Case: Comes with a custom-fitted wooden carrying/storage case. This protects the precision surfaces of the block from physical damage, dust, and environmental factors, preserving its accuracy and extending its lifespan, while also providing convenient portability.

• Essential for NDT Certification & Training: A cornerstone block for NDT training schools, certification exams, and for daily use by certified ultrasonic technicians in the field.

• PH TOOL Quality: As a product from PH TOOL, a globally recognized leader in NDT reference standards, you are guaranteed unparalleled precision and adherence to specifications.
