MIL-PRF-85285 §4.5.1 Test Panels

Test panels used in testing by MIL-PRF-85285 (Polyurethane Coating: Aircraft and Support Equipment - Performance Specification). These test panels are prepared as described in MIL-PRF-85285 §4.5.1. The panels are made from 2024-T3 bare aluminum, and each panel is 3" x 6" x 0.020". The panels are coated in accordance with MIL-DTL-5541 Class 1A.


Metaspec provides these test panels with an as rolled surface finish or with the MIL-DTL-5541 coating.

  • 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.
