Thanks for that Jack especially for the allowable tolerance.
Another question regarding saturation graphs. AMS 2430 states to check intensity verification periodically. I take it we would re run saturation graphs if we were getting abnormal results, after changing anything such as blast hoses, nozzles , valves etc, but what would be considered an acceptable time frame if non of the above has happened?
We also peen one off parts with radically different diameters throughout the day requiring individual saturation graphs. To reduce the amount of variables we attempt to peen using the same pounds, traverse rates, distance from part, etc and to allow for the different diameters we are using the same circumferential velocity.
Am I able to peen one graph to cover all the parts with the same intensity parameters to cover the requirement for periodical checking?
