Set of calibration blocks KMD2-0 as per GOST 23667

The set of calibration blocks KMD 2-0 is intended for measuring the parameters of ultrasonic pulse flaw detectors as per GOST 23667.

Main specifications

The set consists of two calibration blocks: MD 2-0-1 and MD 2-0-2. The blocks from KMD 2-0 set are based on 40Х13 steel plate. They contain artificial reflectors such as side drilled holes diam. 1.6 mm (for MD2-0-1) or 1.0 mm (for MD2-0-2) that are located at the depth from 0.5 mm to 50 mm.

Main specifications of these calibration blocks are listed in the Table below:
