Comparison of Vee notch and U notch response

We have historically used the EDM u-notch for our calibration reflector when testing nuclear-grade zirconium rod. The rod has diameter of 8 to 25 mm, with notch depths of about .25mm. We recently have had a number of customers request the use of the vee notch for standards on new orders. Is there anyone who knows of comparison data on the responses from vee and U notches? I would greatly appreciate being pointed in the right direction for that information.

Re: Comparison of Vee notch and U notch response
David,

PH Tool Reference Standards manufactures EDM notch standards for NDT. We machine both "U" and "Vee-shaped" notches on ODs (and even IDs), oriented longitudinally and circumferentially. I have no response data cpmparing the two types, but would be glad to discuss the machining of various notch types on your supplied zirconium rod.

mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
