J2277_200910 Shot Peening Coverage Determination

The title has been expanded (include word “Determination” to indicate that this standard practice relates to a method of inspection, but does not govern the amount of coverage to be achieved. Section 3.2 is included to help quantify the mathematical nature of peening coverage. It is adapted from SAE J443 published in 1961. Section 4.5 Coverage Coupon is included to allow an alternative coverage rate determination method which may be useful in situations where the peening dent is very small and thus very hard to observe such as for high hardness parts or for parts peened at very low intensities.
