Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The size of the sample shall be negotiated between the user and the producer. It may be a full cross section but should not be too large for practical handling in the polishing operation.

The rating will be the number of that photo which most closely resembles the appearance of the specimen. Higher numbers indicate a larger number or greater degree of severity of the category being rated. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

A superscript epsilon e indicates an editorial change since the last revision or reapproval.
