Application
V1 Calibration Block is designed for verification of the ultrasonic flaw detectors used in the course of welded joints quality control by the UT method. It is DSTU 4002-2000 (ISO 2400, DIN 54120, B.S. 2704) compliant.
This product does not have additional information.
V1 Calibration Block allows:
- to determine the UT beam index and X-value with an error of ±0.5 mm
- to determine the probe angle of the ultrasonic wave with an error of ±1 ang. degr.
- to determine uncontrolled (“dead zone”) of the ultrasonic straight beam piezoelectric probes in steel
- to determine resolution (in steel) of the ultrasonic straight beam piezoelectric probes
- to determine the scan horizontal linearity of the ultrasonic flaw detectors
- to adjust the scan speed and sensitivity of the straight beam, double crystal, angle beam piezoelectric transducers
