PAUT IIW Calibration Block ISO 19675 300 × 100 × 25 mm

PH Tool is proud to be the first US-based manufacturer to offer the PAUT IIW Block to the NDT market, providing design input during the development of the new specification. Our calibration blocks meet the exacting requirements of ISO 19675 for calibrating Phased Array and Conventional Ultrasonic flaw detection equipment.

• Probe index and beam angle verification
• Beam squint angle assessment
• Time base linearity and calibration
• Attenuator linearity testing
• Screen height linearity verification
• Pulse duration measurement
• Dominant frequency measurement
• Signal-to-noise ratio (SNR) assessment
• Wedge delay calibration
• Grating lobe assessment
• Active element evaluation
• Sensitivity equalization for E-scans and S-scans
• Plotting verification
• Element assignment confirmation
• Anisotropy assessment

Our manufacturing process begins with high-quality, fine-grained steel produced to special specifications. Each block undergoes comprehensive processing including heat treatment, flaw detection, material attenuation checks, velocity measurements (longitudinal and transverse wave), precision machining, surface finish preparation, block identification, in-house nickel-plating, and thorough documentation.

Each PAUT IIW Calibration Block ships with complete documentation:

• PH Tool NIST-traceable Certification Report confirming conformance to ISO 19675
• Material Test Report for raw material traceability
• PMI Test Report with chemical analysis via XRF testing
• Dimensional Report with measured physical dimensions and hole diameters
• Material attenuation results per specification paragraph 5.2.3
• Velocity measurements in accordance with Annex A specifications
