3" x 6" 2024-T0 aluminum panel anodized MIL-A-8625 for MIL-PRF-85285 flexibility test

MIL-PRF-85285 §4.6.7 Flexibility Test Panels

Test panels used in flexibility testing by MIL-PRF-85285F (Polyurethane Coating: Aircraft and Support Equipment - Performance Specification). These panels are used in the Impact Flexibility and the Low-temperature Flexibility tests. Each panel is made of 2024-T0 bare aluminum (AMS 4035), and is 3" x 6" 0.020". Before testing, the panels are anodized in accordance with MIL-A-8625 Type I (Unsealed). 


Metaspec provides these test panels with an as rolled surface finish or with the MIL-A-8625 unsealed anodized finish.

  • 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.
