Abstract:  
This specification establishes the engineering requirements for computer monitored peening of surfaces of parts. This procedure has been used typically to induce, through cold working, a surface layer that is residually stressed in compression thereby enhancing fatigue performance and resistance to stress-corrosion cracking, corrosion fatigue, fretting fatigue, spalling, and galling and to provide a means by which the shot peening process can be performed on parts which rely on the benefits provided by shot peening in order to satisfy material component design, but usage is not limited to such applications. Shot peening in conformance with this specification requires that locations of intensity verification (Almen test strip locations) be shown on the drawing. Processes such as tumbling of parts in peening, slurry peening, peen forming and straightening, peening for prevention of intergranular corrosion, and peening to produce a surface texture are recognized but their requirements are not covered.
