4.1 The procedures outlined in this practice are designed to standardize the test specimens, surface preparations, combinations of materials, and adhesive selection. Because of the flexibility in the procedure, it is important to have some idea of the kind of properties that will be observed during testing.

1.1 This practice describes bar- and rod-type butt-joined adhesion test specimens and procedures for preparing and bonding them. The specimens are intended to be used with various adherend materials in like or unlike combinations for determining the strength properties of adhesives in accordance with Test Method D2095.

1.2 The values stated in SI units are considered to be the standard. The values in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
