Shot peening coverage is confirmed by mounting a test strip having surface irregularities of graduated depth on a surface of a component undergoing peening for which peening coverage is to be confirmed. The component, with the test strip attached thereto, is exposed to the shot stream under production conditions. The strip, which is selected according to a procedure described herein such that some, but not all, of the surface irregularities are removed when proper peening coverage is attained, is then removed and examined.

1. Test strip for establishing shot peening coverage, said strip having opposite surfaces, one of said surfaces being a substantially flat surface and the opposite surface being a textured surface defining irregularities of a predetermined depth, said strip having a thickness sufficient that said strip does not deflect during normal shot peening. 2. Test strip as claimed in claim 1, wherein said irregularities on said textured surface are distributed in a uniform pattern across the textured surface. 3. Test strip as claimed in claim 2, wherein said irregularities are of a substantially constant depth. 4. Test strip as claimed in claim 3, wherein said irregularities are defined by striations. 5. Test strip as claimed in claim 1, wherein said textured surface includes multiple sections of irregularities, the depth of the irregularities of each section being unequal to the depth of the irregularities of an adjoining section. 6. Test strip as claimed in claim 5, wherein said irregularities are defined by striations, the striations in adjoining sections being oriented to extend in a direction different from the orientation of the striations in an adjoining section. 7. Test strip as claimed in claim 1, wherein said irregularities are defined by striations. 8. Test strip for establishing shot peening coverage, said strip having opposite surfaces, one of said surfaces being a substantially flat surface and the opposite surface being multiple sections of textured surface, each section of textured surface defining irregularities of a predetermined depth, the depth of the irregularities of each of said multiple sections being unequal to the depth of the irregularities of an adjoining section. 9. Test strip as claimed in claim 8, wherein said irregularities are defined by striations, the striations in adjoining sections being oriented to extend in a direction different from the orientation of the striations in an adjoining section. 10. Method of confirming that a component undergoing shot peening has attained a predetermined peening coverage comprising the steps of mounting a testing test strip having a test surface having surface irregularities in a predetermined pattern on a component the peening coverage of which is to be confirmed, said surface irregularities being modified when the predetermined peening coverage is attained, peening the component at a predetermined intensity, and examining the testing test strip to confirm peening coverage, said test strip including multiple sections of surface irregularities, the irregularities of each section having a pattern distinct from the irregularities in an adjacent section. 11. Method of confirming that a component undergoing shot peening has attained a predetermined peening coverage comprising the steps of mounting a testing test strip having a test surface having surface irregularities in a predetermined pattern on a component the peening coverage of which is to be confirmed, said surface irregularities being modified when the predetermined peening coverage is attained, peening the component at a predetermined intensity, and examining the testing test strip to confirm peening coverage, said test strip including multiple sections of surface irregularities, said step of examining said test strip including the step of noting that predetermined sections of said test strip have been obliterated to indicate satisfactory peening coverage.
