Scope:

This SAE Recommended Practice provides procedures for determining shot peening coverage. Effectiveness of shot peening is directly dependent on coverage. Inadequate or excessive coverage may be detrimental to fatigue strength and life.

Rationale:

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 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.
