Calibration K1 Block (Metric Version) Special Alloy  

K1 Block are used to calibrate instruments for both angle beam and normal incident inspections. Some of their uses include setting metal-distance and sensitivity settings, determining the sound exit point and refracted angle of angle beam transducers, and evaluating depth resolution of normal beam inspection setups.

For calibrating ultrasonic flaw detection equipment in both laboratory and on-site conditions. Our version of this block includes a 100mm radius, 3.0mm and 50.0mm holes, engraved reference mark scales, and two optional slots at the zero point which provide calibrating signals at intervals of 100mm range. In accordance with EN 12223 and ISO 2400. 

This block is not to be confused with the older style "V1/5 (A2)" Block from BS 2704, which is similar but contains a 1.5mm through-hole rather than a 3.0mm hole. See our test block store for more information on this block.

Geometry: 100mm radius, 3.0mm and 50.0mm holes, engraved reference mark scales, and two optional slots at the zero point which provide calibrating signals at intervals of 100mm range.

Dimensions: 300mm x 100mm x 25mm.
