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. Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive.

This will be based on a visual inspection. The grips shall be attached to the?

Adhesion failure refers to the lack of adhering to metals being fastened. Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive. This standard has been approved for use by agencies of the Department of Defense.

It is preferable to grind all metal specimens at the same time.
