Cut test specimen approximately 7.5 x 15 cm from the sample part. If the part is smaller than 3 x 6 inches, the test specimen shall be as large a s possible.

    8、 Remove loose particles from the cut edges with file or knife. 2. Remove any paint, soil, vinyl and finger prints with solvent. 3. Determine the anodic film thickness with a light section microscope. See FLTM BQ 010 - 01 for method. Alternate ly, if a destructive thickness test is used, a suitable s
