MIL-PRF-16173 §4.6.8 Corrosion Test Specimens
Corrosion test specimens used in testing by military specification MIL-PRF-16173 §4.6.8. The test specimens are made from brass, zinc, magnesium, aluminum (2024-T3 bare and 2024-T3 clad), steel, and lead-calcium alloy. Each specimen is 1/4" x 7/8" x 2" and has a small hole drilled in one corner. This test method requires two sets of seven specimens (one of each alloy). All the specimens are cleaned and polished on all faces and edges (240 grit).
