ASTM B137 Aluminum Test Specimens
Aluminum test specimens and panels used in ASTM B137 (Measurement of Coating Mass Per Unit Area on Anodically Coated Aluminum). Each aluminum test specimen is 75 mm square (2.95" x 2.95"). Metaspec makes these test specimens with an as-rolled surface finish (not anodized). Customized test specimens (different sizes or different surface finishes) 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.
