ASTM D3167: Standard Test Method for Floating Roller Peel Resistance of Adhesives

ASTM D3167 test method covers the determination of the relative peel resistance of adhesive bonds between one rigid adherend and one flexible adherend when tested under specified conditions of preparation and testing.

ASTM D3167 Floating peel test fixture consists of two roller bearings fixed in a frame, which is connected to the testing system through a rotatable adapter. This design ensures that the specimen is immediately aligned when force is applied, and the applied force is along the centerline of the fixture. When the beam is driven in the tensile direction, the load sensor measures the force required to peel the flexible adhesive off the rigid adhesive.

It is important to note that if there is a variation in thickness of the adherends this will influence the results. Therefore, if no thickness is specified as part of the material specification the following needs to be adhered to: 1, Flexible adherend – 0.63mm thick; 2, Rigid adherend – 1.62mm thick

Test Procedure

The unbonded end of the flexible adhesive is bonded perpendicular to the stiff substance and clamped into the grips according to ASTM D3167. The adhesive specimen is put between the two floating roller fixtures, and the load is applied as required. The test is carried out at a displacement rate according to the testing standard. When the specimen ruptures or breaks, the test is over. At least five additional specimens are required to carry out the test. 

Test Result

In ASTM D3167, Variations in the thickness of the adherents will generally influence the test values. The test results include the average peel strength, calculated from the load versus head movement curve, expressed in pounds-force per inch (or kilonewtons per meter). The report should also include detailed information about the adhesive, materials, bonding process, test conditions, specimen construction, and failure mode (adhesive or cohesive failure). Record the average, maximum, and minimum peeling loads for each specimen.
