Automatic shot peening specification AMS 2430 Rev. R defines peening intensity in par. 3.6.2:
"Peening intensity shall be as specified on the engineering drawing, determined in accordance with SAE J443."
After issuing of new revision of specification SAE J443 Rev. June 2010 the definition of the peening intensity has changed.
The peening almen intensity is now related only to saturation curves, but not to the arc height measured in production lots.
So per par. 7.3 of SAE J443 the arc height may be outside the tolerance required by the blueprint for specific parts and is considered as acceptable by SAE J443.
We see hear contradiction that may influence on the process and produce parts not confirming to the blueprints requirements.
