MIL-PRF-81309 Figure 6 Penetration test panel assembly

MIL-PRF-81309 §4.6.11 Functional Penetration Test Panels

Aluminum test panels used in MIL-PRF-81309 §4.6.11 (Functional Penetration). Each test panel is 3" x 8" x 1/8", with 6 holes as shown in Figure 6. The panels are made from 7075 aluminum. Metaspec provides these test panels with either an as rolled surface finish or with MIL-DTL-5541 chemical conversion (not primed or painted). Customized test panels are available on request.

  • Regular test panels are PVC-coated on both sides, cut to size, deburred, and packed in bundles. These panels may have some minor surface defects and will have mill oil on the surface, as these are the sheets in “as-received” condition from the aluminum mill.
