The DAC Calibration Block is for Setting DAC characteristics for shear wave and compression wave probes. All blocks come will full certification and are manufactured in the UK. Target Holes: 3mm at 20%, 40%, 60% and 80%. Specification: BS EN ISO 17640:2018. Tolerances: ±0.1mm. Thickness: 50mm. Diameter: 50mm. Length: 200mm

PH Tool ASME (DAC) Style ERVW Piping Blocks Only three blocks needed to cover a large range of pipe sizes, which would otherwise require dozens of calibration blocks. More Details >> PH Tool ERVW Pipe Calibration Blocks (Circ, SDHs)

MATERIAL: CARBON STEEL BLOCK DIMENSION: 450MM (L) X 75MM (H) X 50MM (W) BLOCK CONTAINS 4 SIDE DRILL HOLE (SDH) AT ≤5, ≤ T-10/2 DEPTH OF THRU HOLES.

Angle Beam DAC and TCG Calibration. Geometry: Contains 2 slots: One on each face and on three sides are drilled holes 1.5" deep. Diameter of the holes are determined by block thickness.

ASME Sec V Non-Piping Calibration Blocks (DAC Block) Used for establishment of primary reference responses for UT examination of welds. The standard blocks are available in thickness (T) 0.75” (19mm), 1.5” (38mm) and 3” (75mm) which contains three side-drilled holes of diameter 3/32” (2.5mm), 1/8” (3mm) and 3/16” (5mm) respectively.

Distance amplitude correction (DAC) provides a means of establishing a graphic ‘reference level sensitivity’ as a function of sweep distance on the A-scan display. The use of DAC allows signals reflected from similar discontinuities to be evaluated where signal attenuation as a function of depth has been correlated.

Reference Blocks are serialized and supplied with certification traceable to the National Institute of Standards and Technology (NIST) and available in English and metric units. ASTM blocks are supplied with a DAC Report. All certifications are permanently kept …

Blocks used for establishing DAC/TCG calibrations must provide suitable length and strategically placed reference reflectors to avoid conflicting echoes. The dreaded "split-DAC" is often required on shorter blocks which may result in sudden step up/down in the TCG curve.

We manufacture ultrasonic standard and special test blocks and test pieces, all to the most recent and up to date standards including No.1/V1s to EN ISO 2400:2012, No.2/V2s to EN ISO 7963:2010 and Ladder Step Wedges to 16946:2017.
