The test face is the largest surface of the sample. The certified portion of the sample is from the Test Face to a depth of 5/16". Values in parentheses are approximate. Nil; not detected.

Note: These standards are not traceable to NIST or any other standards organizations. They are therefore reference standards. They were prepared by the Malleable Research group who did their own certifications via round robin testing.
