BCS NDT is also specialized in the manufacture of calibration blocks for Ultrasonic and Eddy Current testing. Using appropriate electro-discharge machines BCS NDT manufacture different configurations of artificial defects with a high level of precision, within the tolerances of DNVGL-ST-F101 and ASME V range.
All blocks are provided with:
- Metrological report;
- Certificate of conformance.
AUT Calibration Blocks
AUT calibration blocks in accordance with DNVGL-ST-F101, ASTM1961 and ISO13588 or Client specification. These blocks typically contain: Flat-Bottomed-Holes (FBH) with dimension from 1mm to 3mm; outer and inner surface square notches; V-notches, through holes or notches. The blocks are generally Z-shaped to accommodate J-bevel FBH reflectors.
At the end of the manufacturing process, blocks can be inserted in a dummy to allow for AUT band placement.
PAUT Calibration Blocks
PAUT calibration blocks in accordance with DNVGL-ST-F101, ASME V, ISO13588 containing Side Drilled Holes (SDH), inner notches and outer notches. Block can be inserted in a dummy pipe.
ET Calibration Blocks
External and internal EDM (Electro Discharge Machining) notch on small bore pipes for eddy current application, with width down to 0,2mm.
