The “Flat Ketos” Block measures 0.800″ thick x 3.00″ tall x 7.00″ long, and is used to check overall performance of the magnetic particle examination system. This popular new block has recently been worked into various industry specifications for magnetic particle testing, and is now being offered by PH Tool as a new addition to our extensive line of NDT Test Blocks and Reference Standards.

Capable of indicating smaller subsurface discontinuities than its “ring-shaped” cousin, this block includes (12) thru-holes at 0.040″ diameter at distances of 0.060, 0.080, 0.100, 0.120, 0.160, and 0.200″ from the upper indication surface, and at 0.240, 0.310, 0.390, 0.470, 0.550, and 0.630″ from the lower indication surface. Also known as “Test Block with Artificial Subsurface Discontinuities.” In accordance with PH Tool Drawing No. 10234. Metric Version also available.
