Home Forums General Discussion Ask Dr. Peener 4A intensity "A" strip for saturation graph?

Hi Socrates, I am required to peen a 4A intensity, what sized strip will I use to produce a saturation graph for this?
AM2430 paragraph 3.2.2.2
“A” strips are generally used from 4A to 24A. “N” strip for lower intensity values

Do I still use “A” strips for creating an intensity of 4A?
Will the lower values created while proving the intensity point give a correct saturation graph?

Thanks
