ASTM D903 is a test procedure used to determine the strength of adhesive bonds. It provides guidance on testing standard-sized specimens at precisely controlled test machine speed. A piece of tape or adhesive is bonded to a standard material and peeled backwards at a 180 degree angle. The main calculation determined through this ASTM standard is average peel or stripping strength.
Before conducting ASTM D903, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
