ASTM D2939 Metal Panels & Masks

Metal panels and substrates used in testing by ASTM D2939 (Emulsified Bitumens Used as Protective Coatings). ASTM D2939 describes various test methods to sample and test emulsified bitumens. Many of these tests use the same or similar test panels or substrates. 
 
Metal Panels:
150 mm x 150 mm x 0.3-0.4 mm (6" x 6" x 0.012-0.016")
Available with as-rolled surface finish or polished on one face with 00 steel wool
Used in sections: 13, 14, 15, 16*, 19, 20, 26**, 27**
*Section 16 requires aluminum metal panels
**Section 26 and 27 require metal panels that are 1/8” thick
Brass Mask:
150 mm x 150 mm (6" x 6")
1.6 mm (1/16") or 1/8" thick with 100 mm (4") square opening in center

Black Iron Panel
300 mm x 300 mm x 1.6 mm (12” x 12” x 1/16”)
Cold rolled carbon steel with a clean, rust-free surface
Used in sections: 17, 18
Ceramic Tile Panel
150 mm x 150 mm x 9.5-13 mm (6” x 6” x 3/8-1/2”) (approximate)
