ASTM D1781 – Climbing Drum Peel for Adhesives

To request a quotation for any test email for a prompt reply

This test method covers the determination of the peel resistance of adhesive bonds between a relatively flexible adherend and a rigid adherend as well as a relatively flexible facing of a sandwich structure and its core.

In order to determine the peeling force of a conditioned adhesive bonded sandwich assembly, the face skin is peeled around an acircular drum. This is done by clamping the assembly into the test machine and as the test is being performed, the load is monitored. From this data, an average peeling load is determined.

This test method may be used to determine comparative measurements of adhesion.

Please email or call (304) 547-5800 for information regarding test procedures, results, specimen information, pricing or any other ASTM 1781 questions you may have.
