Hi Walter, Jack,

It s the customer s requirement. Its shown on their process requirements drawings that no maskings were used. Hence i think it s an issue of "how it s always been done".

But my other concern is how interpret intensity within the tolerance range for multiple almen holders (as acceptable) under AMS2430. Change of process engineer , change of intepretation. If the required range is 4-7N

1)you get 4N, 5N,6.5N for 3 almen holders , Is that considered all within range and to spec

2)You have to get 3 intensities that's 0.0015inches of each other within the tolerance range.

Number 2 is probably the best way to go, but just wondering if number 1 is considered wrong?
