The Electronics Inc. (EI) mini-strip will verify shot peening intensity in areas that are too small and/or inaccessible with a standard-size Almen strip and holder. This approach replaces the laborious shaded-strip procedure with a faster and more accurate process. Shot peening technicians in aerospace and spring and gear manufacturers will appreciate the ease and convenience of the new process. The mini-strips measure 1” x 1/8” (25.4 mm x 3.175 mm) and can be attached with double-sided tape directly to a test component or simulated fixture—no need to allow room for a standard Almen holder. Plus, they’re ready-to-go—no need to make a shaded strip. Their small size makes them ideal for measuring intensity in small or hard-to-reach areas like dove-tail slots in jet engine disks, gear roots, and the internal bore of springs, without creating a complicated test fixture. The EI mini-strips must be used with the EI TSP-M gage.

The EI mini-strips are compliant to SAE J442.
