Mike,
PH Tool Reference Standards has made Magnetic Particle Inspection standards containing EDM notches for Navy customers who have painted them after our EDM work. The notches should be extremely narrow (.0015-.003") to best simulate real cracks and should be epoxy-filled to prevent mechanical holding. The epoxy is applied after EDM and before painting. You can specify any notch length, depth, orientation, and location you prefer. Hope this helps. We are happy to help or further advise if needed.
Best Regards,
Phil Herman Jr.

: I am interested in any qualification activities or information regarding magnetic particle testing through paint. We have a particular application where coating removal is costly and difficult. We are considering manufacturing a standard with EDM notches. Any experience?
