ASTM D() is used to measure the strength of a cured bond. This is a critical property of any adhesive, as they can exhibit unique shear properties. In this paper, the shear strengths of two acrylic adhesives were evaluated using the lap shear test method ASTM D and the block shear test method ASTM. ASTM D(). Standard Test Method for Determining Strength of Adhesively Bonded Rigid Plastic Lap-Shear Joints in Shear by.
